Subject: [PATCH v6 04/13] wifi: ath11k: update regulatory rules when interface added

There are two power types for 6 GHz regulatory, one is AP, another
is client.

When wlan boot 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 ath11k select reg rules of AP type as default.

After interface is created, it is exactly decided the interface
type such as AP/mesh point/station. Then ath11k need to update
reg rules to the exact power type matched to the interface type.

The client power type is used for station interface, and AP power
type is used for AP/mesh point interface.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
