qcacld-3.0: Refine interface combinations advertised in wiphy

Currently, interface combinations are advertised as part of wiphy
registration but some of them lead to 3-port/4-port. Refine the
concurrencies to advertise only supported combinations as below,
1. Remove SAP+SAP_MAX_OBSS_STA combination
2. Remove the "reserved STA iface which was added to support
   P2P device". No need to indicate any additional interface count
   for P2P_DEVICE mode as driver doesn't advertise dedicated
   P2P_DEVICE support.
3. Add NAN+STA and NAN+SAP combinations also.
