During bootup, WMI_REG_CHAN_LIST_CC_EXT_EVENTID event sent from firmware
at an early stage and it expects the 6 GHz power type for 6 GHz reg rules.
As power mode is not defined at this point host selects IEEE80211_REG_UNSET_AP
as default mode.
When interface is created, it updates regd rules accordingly.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
