Currently, PCL returns all 5 GHz channel and SCC channel for SAP
when an ML-STA is present. But this may lead to a case
where the CSA request might be for a DFS channel which needs CAC.
This needs a dedicated mac and ML-STA can't move to MLMR in such
cases. When firmware attempts to move STA to MLMR from MLSR,
firmware asserts as the other mac is occupied by DFS SAP for
CAC operation.
So, allow CSA to a DFS channel only if the channel is present in
PCL list as it covers the supported channel list anyway. Fix
policy mgr table entries also by allowing SCC channels only.
