Series wifi: rtw89: 8852b: add RF calibration part 1 | expand

Commit Message

Ping-Ke Shih Oct. 12, 2022, 8:32 a.m. UTC 
IQ signal calibration is a very important calibration to yield good RF
performance. We do this calibration only if we are going to run on AP
channel. During scanning phase, without this calibration RF performance
is still acceptable because it transmits with low data rate at this phase.
