wifi: rtw89: phy: set CFR to manual mode for some 2GHz channels

Browse Source 
The CFR (Channel Frequency Response) manual mode condition for 2GHz is
missing to limit on bandwidth for specific channels, which are channel
13 with 20MHz bandwidth and channel 11 with 40MHz bandwidth. Also add
a band check to avoid affecting 5GHz/6GHz bands.
