wifi: mac80211: batch recalc during STA flush

When we flush stations, we first take them off the list
and then destroy them one by one. If we do the different
mode recalculations while destroying them, we cause the
following scenario:
 - STA 1 has 80 MHz - min chanctx width is now 80 MHz
 - STA 2 has 80 MHz
 - empty STA list
 - destroy STA 2
 - recalc min chanctx width -> results in 20 MHz as
   the STA list is already empty

This is broken, since as far as the driver is concerned
STA 1 still exists at this point, and this causes issues
at least with iwlwifi.

Fix - and also optimize - this by doing the recalc of
min chanctx width (and also P2P PS) only after all the
stations were removed.

wifi: mac80211: fix switch count in EMA beacons

Currently, whenever an EMA beacon is formed, due to is_template
argument being false from the caller, the switch count is always
decremented once which is wrong.

Also if switch count is equal to profile periodicity, this makes
the switch count to reach till zero which triggers a WARN_ON_ONCE.

wifi: mac80211: mlme: fix non-inheritence element

There were two bugs when creating the non-inheritence
element:
 1) 'at_extension' needs to be declared outside the loop,
    otherwise the value resets every iteration and we
    can never really switch properly
 2) 'added' never got set to true, so we always cut off
    the extension element again at the end of the function

This shows another issue that we might add a list but no
extension list, but we need to make the extension list a
zero-length one in that case.

Fix all these issues. While at it, add a comment explaining
the trim.

wifi: rtw89: use struct to access register-based H2C/C2H

The register-based H2C/C2H are used to exchange commands and events with
firmware. The exchange data is limited, but it is relatively simple,
because it can work before HCI initialization. To make these code clean,
use struct to access them. This patch doesn't change logic at all.

RX descriptor is to provide basic and important information related to

wifi: rtw89: add chip_ops::query_rxdesc() and rxd_len as helpers to support newer chips

The next generation chips use different RX descriptor format, so add
a chip_ops to hook suitable handlers. Also, the length of RX descriptor is
different, so add a variable to store the length according to chip and
descriptor content dynamically. Then, the code can be more general.

wifi: rtw89: enlarge supported length of read_reg debugfs entry

The register ranges of upcoming chips are different from current, and even
existing chips have different ranges, so support longer length to dump
registers. Then, user space can decide the ranges according to chip.

Since arbitrary length (e.g. 7) would be a little complicated, so simply
make length a multiple of 16. The output looks like
