qcacmn: Add support to allow user select preferred band for SAP

Add enum QDF_MCC_TO_SCC_WITH_PREFERRED_BAND(6) for this.
If ini gWlanMccToSccSwitchMode is selected to
QDF_MCC_TO_SCC_WITH_PREFERRED_BAND(6) then following will be the
behaviour of STA+SAP concurrency.
1. If second interface(SAP/STA) comes in same band as
   first interface(STA/SAP) respectively then force SCC
   irrespective of channel.
2. If second interface(SAP/STA) comes in other band as
   first interface(STA/SAP) then dont force SCC allow
   interband MCC or DBS based on DBS capability.
Allow interband MCC but not intraband MCC.
