qcacld-3.0: Avoid STA CSA to disallowed channel

STA is on 5 GHz 5260, SAP on 6 GHz 6415, GO on 5 GHz 5745.
STA receives CSA event to move to 5540. Then 3 vdevs are
MCC in 5 GHz high band which is not supported by target.
And we should avoid SAP+GO on same band MCC.
Fix by:
1. Check allow concurrency for STA CSA for more than 2 connection
case.
2. change SAP PCL to only includes SCC 5 GHz channel and 2.4
GHz channel to avoid SAP choosing 5 GHz MCC channel if STA+GO is in
SBS mode.
