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.
