In order to reuse mt7615 code adding support for mt7663e driver,
introduce mt7615e_reg_map since mt7663e and mt7615 rely on a
different base registers definitions.

and reg_val share the same cache-line, resulting in the following crash:

0e544cb59c mt76: mt7615: rework rx phy index handling
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.

35492cd28f mt76: mt7615: add support for testing hardware reset
Send an undersized corrupt packet to the DMA queue, which causes the
firmware to issue a full chip reset

61c4fa7219 mt76: mt7615: implement hardware reset support
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.

15d9a5d7b5 mt76: mt7615: fix and rework tx power handling
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.
