Subject: [PATCH] ath11k: Add support to parse new wmi event for 6G regulatory
In order to support different power levels of 6G AP and client, new
wmi event for regulatory is added in FW (WMI_REG_CHAN_LIST_CC_EXT_EVENTID)
to provide new parameters required for 6G regulatory rules.
FW 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 new wmi event.
Based on advertised host capability, FW decides to send old event
(WMI_REG_CHAN_LIST_CC_EVENTID) or new event(WMI_REG_CHAN_LIST_CC_EXT_EVENTID).
Added support for parsing 2G/5G/6G reg rules and other parameters from
WMI_REG_CHAN_LIST_CC_EXT_EVENTID, to populate the channel lists.
Since 6G requires additional power value fields(PSD info), reg rule parsing
function is updated accordingly to handle it.
