wireless: add plfxlc driver for pureLiFi X, XL, XC devices

This is a driver for pureLiFi X, XL, XC devices which use light to transmit
data, so they are not compatible with normal Wi-Fi devices. The driver uses
separate NL80211_BAND_LC band to distinguish from Wi-Fi.  The driver is based
on 802.11 softMAC Architecture and uses native 802.11 for configuration and
management. Station and Ad-Hoc modes are supported.

The driver is compiled and tested in ARM, x86 architectures and compiled in
powerpc architecture. This driver implementation has been based on the zd1211rw
driver.

rtw89: 8852c: implement chip_ops related to TX power

Three chip_ops are implemented in this patch. The ::set_txpwr_ctrl and
::init_txpwr_unit are called when we up interface and then configure TX
power registers to initial values. The ::set_txpwr_ctrl is to configure
'txpwr_ref' to make basic output TX power of OFDM and CCK rate to be the
same. The ::init_txpwr_unit is to initialize TSSI (a method to do TX power
compensation depends on thermal value) control and bandedge.

The ::set_txpwr is called once switching channel. First, it sets TX power
for each rate section (e.g. CCK, OFDM), and then sets TX power offset
between 1SS and 2SS rate. Finally, it sets TX power limit to prevent
power over regulation.

rtw89: ps: access TX/RX rings via another registers in low power mode

In low power mode, we need to pause PCI to configure IMR and PCI ring
index registers accordingly, because the regular registers are power-off
in this mode.

In the transition moment named paused in code, we can't touch ring index,
so don't kick off DMA immediately. Instead, queue them into pending queue,
and kick off after the moment.

There are three low power modes, which are RF off/clock gate/power gate,
but PCI enter low power mode in later two modes only. So, add a mask
to achieve this.

rtw88: Add update beacon flow for AP mode

To support stations in power saving mode, AP should notify stations
that there are frames buffered at the AP via TIM during beacons.
Driver used to transmit identical beacons that were downloaded to
hardware during the initiation phase. This beacon will become
obsolete over time.

If the beacon does not contain sufficient information, station would
not be able to percept that there is data to receive. Hence it won't
wake up and start the PS-poll procedure, this could lead to timeout
and/or lost data segments. In order to resolve this issue, driver will
now download beacon to hardware whenever the content is updated.

Enable hardware to update dtim_count for more efficiency, this reduces
the overhead of downloading beacon at every beacon interval since most
of the time only the dtim_count needs to be updated.

Change queue mapping for broadcast/multicast frames to high queue, so
these frames can be prioritized and sent when dtim_count is zero.

mac80211: prepare sta handling for MLO support

Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.

With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.

To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.

For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.

For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.

Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.

Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

rtlwifi: replace usage of found with dedicated list iterator variable

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].

This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

brcmfmac: Avoid keeping power to SDIO card unless WOWL is used

Keeping the power to the SDIO card during system wide suspend, consumes
energy. Especially on battery driven embedded systems, this can be a
problem. Therefore, let's change the behaviour into allowing the SDIO card
to be powered off, unless WOWL is supported and enabled.

Note that, the downside from this change, is that during system resume the
SDIO card needs to be re-initialized and the FW must be re-programmed. Even
if this may take some time to complete, it should we worth it, rather than
draining the battery.

mwifiex: add mutex lock for call in mwifiex_dfs_chan_sw_work_queue

cfg80211_ch_switch_notify uses ASSERT_WDEV_LOCK to assert that
net_device->ieee80211_ptr->mtx (which is the same as priv->wdev.mtx)
is held during the function's execution.
mwifiex_dfs_chan_sw_work_queue is one of its callers, which does not
hold that lock, therefore violating the assertion.
Add a lock around the call.

Disclaimer:
I am currently working on a static analyser to detect missing locks.
This was a reported case. I manually verified the report by looking
at the code, so that I do not send wrong information or patches.
After concluding that this seems to be a true positive, I created
this patch.
However, as I do not in fact have this particular hardware,
I was unable to test it.
