TXWI, RXWI sizes are not RF chipset properties. Similar like vendor
driver please introduce RT6352 (set chip.rt = RT6352 on init)
and use it when need to identify RT chip instead of mixing RT
checks and RF checks. There are few places below where this
need to be changed, I pointed some but not all.
BTW, I wondered where all this low level settings came from until
I realized that vendor driver use RT6352 name, that was confusing.

Vendor driver make this quite different. It use different procedure
on initialization than we do rt2800_init_rx_filter and use different
values for TX and RX. See BW_Filter_Calibration() and
RT6352_ChipSwitchChannel().
For now we can apply this, but need to be fixed in the future.

I think this will not cause problems on other chipsets, but I would
be careful here. Having tx_pin = 0 is a problem for MT7620 ?

It should D << 8, but it does not matter since values are 0.
You can just remove those from rf_vals and use 0 for K & D
on rt2800_config_channel_rf7620().
