wifi: ath12k: update regulatory rules when interface added 



There are two power types for 6 GHz regulatory, one is AP, another is
client. The client power type is used for station interface, and AP
power type is used for AP/mesh point interface.

When firmware boots up, WMI_REG_CHAN_LIST_CC_EXT_EVENTID is sent from
firmware at an early stage, the interface mode is not decided at this
point, then ath12k select reg rules of AP type as default.

After interface created, ath12k needs to update reg rules to the exact
power type matching the interface type.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
