Subject: [PATCH] rtw88: coex: update WLAN 5G AFH parameter for 8822b
Adaptive Frequency Hopping(AFH) is a method of transmitting
radio signals by rapidly changing the carrier frequency among
many distinct frequencies, which can avoid interference.
Add this feature to update AFH parameter for 8822b.
