qcacmn: Add MCL/SAP DCS process after AFC event update

When AFC event come and update 6 GHz SP channels' state and power
attribution, SAP which already started on 5 GHz or 6 GHz channel
can move in or out from SP channel, which has higher tx power limit.

SAP target channel/bandwidth is decided by ACS channel select callback
register to SAP module, which will take channel max tx power limit
into account.

After target channel/bandwidth determined, SAPs move to same target
channel/bandwidth with eCSA process. If violate any concurrency
limitation, AFC DCS process should abort.

Add AFC component id and reference id.
