wifi: rtw89: rfk: add H2C command to trigger IQK
IQ signal calibration is a basic and important calibration to yield good RF
performance. Do this calibration on AP channel if we are going to connect.
During scanning phase, it transmits with low data rate, so without IQK
RF performance is still acceptable.
