As previous devices, mt7622 relies on multiple hw queues while for
mt7615 we have just on per band hw queue and the mcu demux the traffic
according to the packet AC. In order to dump all configured hw queues,
rely on mt76_queues_read for mt7622 in mt7615 debugfs

Overwriting the RMAC_CHFREQ register is not reliable enough, as the firmware
could potentially write it again.
Since there is no PHY index indication in the rx info, we need to use another
way:
If both PHYs are using different channels, find the PHY where chfreq matches
the register value.
The only corner case remaining is when both PHYs are using the same channel.
In that case, the per-packet noise value on the primary PHY will have
information belonging to the chains of the secondary PHY from the previous
received packet of that PHY. The secondary PHY will set noise to 0 for extra
chains.

Unify code converting between the different txpower values. Always add/remove
the combined txpower delta before dividing half-dB values.
Also fix the combined txpower delta values. The correct half-dB delta for
3 chains is 9, not 8.

When the firmware detects a problem, it needs the host to stop/reset DMA and
resume it again when the hardware state has been reset.

Setting the tx power by manipulating EEPROM may in some cases not be enough,
since it only covers the base target power and not per-rate offsets.
In other cases, it could limit tx power of rates too much, possibly reducing
throughput or range.
Use firmware support for applying per-rate limit and power offsets for
different values of Nss.

MT7622 does not have the CR4 microcontroller sitting in the data path.
Because of that, it uses the chip's native tx descriptor format instead of
something parsed and converted by the firmware.
