iwlwifi: mvm: Consider P2P GO operation during scan

A scan during active P2P GO operation, i.e., data traffic with
clients, can impact the throughput and latency of such traffic.
Thus, when scan is requested while there is an active P2P GO
and low latency is asserted:

- Ask the FW scan logic to respect the P2P GO activity during the
  scheduling of the scan operation to minimize the impact on the
  throughput and latency.
- Force scan to perform EBS before starting the scan to reduce the
  number of scanned channels.

Most of this change is a continuation of commit 403ea939ea6a
("iwlwifi: dbg: Mark ucode tlv data as const") propagating the
(const) type qualifier for ucode based tlv data to avoid having

The other part of the change preserves the (const) type qualifier
over casts and function calls where it was previously lost.
Both changes are needed to avoid compile time errors on system with

In order to de-const variables simply casting through (void *) is
not enough: "cast from 'const .. *' to 'void *' drops const qualifier".
Cast through (uintptr_t) as well [1] to make this compile on systems
with more strict requirements.
In addition passing const void *data to dma_map_single() also
drops the (const) qualifier.  De-constify on variable on assignment
which may be overwritten later.  In either case the (void *) cast
to dma_map_single() is not needed (anymore) either.

iwlwifi: make iwl_fw_lookup_cmd_ver() take a cmd_id

Instead of taking the group/command separately, make the function
take a combined command ID. In many cases, this allows us to pass
an existing command ID (e.g. cmd.id), or introduce a new variable
for it, so that we don't use the command ID twice.

This way, we can also use LONG_GROUP implicitly, so we don't need
to spell that out for many commands.

Although this practically only points to the address and the actual

brcmfmac: Add BCM43454/6 support

BCM43454/6 is a variant of BCM4345 which is exactly identical to
BCM4345/6, except the chip id is 0xa9be. This patch adds support
for BCM43454/6 by handing it in the same way as BCM4345.

Note: when loading some specific version of BCM4345 firmware, the
chip id may become 0x4345. This is an expected behavior, and it will
restore to 0xa9be after power cycle.
