Series wifi: rtw89: add hardware rate v1 and adjust related things for WiFi 7 | expand

Commit Message

Ping-Ke Shih July 28, 2023, 7:02 a.m. UTC 
RA (rate adaptive) H2C command is used to tell firmware which rates can
be used for specified MAC ID. Basically, this commit doesn't change result.
Only change to set two 32-bit instead of continual 8-byte rate masks one
by one. Originally, we only set 5-byte masks, because existing WiFi 6
2SS chips only need 5-byte masks. Setting two 32-bit masks will be more
efficient and also can support coming WiFi 7 2SS chips containing more
rates.
