rtw88: 8822c: update channel and bandwidth BB setting
In 2G channels, the cck source and rxagc should be set to different
values based on different bandwidth to increase the performance of rx
sensitivity.
To improve rx throughput performance, the values of sbd subtune and
pt_opt should be changed in different bandwidth.
