rtw89: 8852c: add set channel of BB part

BB does many settings during setting channel. First is to configure CCK
for 2G channels, and then basic channel and bandwidth settings with a
encoded channel index that will report to driver when we receive packets.
Configure spur elimination to avoid spur of CSI and NBI tones in certain
frequencies. Also, it initializes BT grant to arrange path sharing with
BT according to band. Finally, reset TSSI and BB hardware to ensure it
stays in initial state.
