wifi: mt76: mt7996: add support for variants with auxiliary RX path

Add support to correctly configure the rx chainmask of variants that
have additional auxiliary RX path. e.g., 4T5R.
The auxiliary RX path is transparent to driver, but driver needs to
correctly configure it in the set channel fw command.

wifi: mt76: mt7996: add driver for MediaTek Wi-Fi 7 (802.11be) devices

The driver first supports Filogic 680 PCI device, which is a Wi-Fi 7
chipset supporting concurrent tri-band operation at 6 GHz, 5 GHz, and
2.4 GHz with 4x4 antennas on each band.

Currently, mt7996 only supports tri-band HE or older mode.
EHT mode and more variants of Filogic 680 support will be introduced
in further patches.
