rtwn: fix rtl8812/rtl8821 vht definitions, add VHT calibration/rate control

[adrian]

Summary

• Add support for 80MHz channels during IQ calibration
• Correct the RAID flags for 1 and 2 stream VHT - the later ones are for 2GHz VHT and then 3/4 stream VHT
• Add VHT to the RAID calculation for when we eventually transmit VHT rates.

Still TODO 160 MHz?

As far as I'm aware, the 8812/8821 don't do 160MHz. If someone finds evidence to the contrary then please lemme know!

I think the only 8821 I found with 160Mhz was a CE and that is rtw88

Are all VHT40 channels also marked HT40?

could be a Phab issue but indentation is weird here.

don't need to make these blocks {} {}

I think so; I don't think we're fully doing greenfield VHT right now.

But honestly it's a good question for the future - going through and adding IS_CHAN_HT{20,40} || IS_CHAN_VHT{20,40} and also IS_CHAN_HT || IS_CHAN_VHT isn't a terrible idea. Lemme go look.
