From: P Praneesh <quic_ppranees at quicinc.com>
In order to support different power levels of 6 GHz AP and client,
new WMI event for regulatory (WMI_REG_CHAN_LIST_CC_EXT_EVENTID) has been
added in firmware to provide new parameters required for 6 GHz regulatory rules.
Firmware advertises its capability of handling new event in WMI service ready
event. Based on that, host needs to set host_service_flags in WMI init command
to indicate that host supports processing of this WMI event.
Based on advertised host capability, firmware sends event (WMI_REG_CHAN_LIST_CC_EXT_EVENTID).
This new event contains 2G/5G/6G reg rules with additional power value
fields for 6GHz and regd is built accordingly.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0-02903-QCAHKSWPL_SILICONZ-1
