ath10k:New interface to get interface combinations from FW

New wmi event "WMI_TLV_IFACE_COMBINATION_EVENTID" is used.
If WMI_SERVICE_IFACE_COMBINATION_SUPPORT service bit set and
WMI_TLV_IFACE_COMBINATION_EVENTID event got from FW side, then
interface combinations reported from FW will override the default
combinations which is hard-coded in host drivers.
