wifi: ath11k: add support to parse new WMI event for 6 GHz

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 is
added in firmware. This event provides new parameters required for
6 GHz regulatory rules.

Add support for parsing 2.4 GHz, 5 GHz and 6 GHz reg rules and other
parameters from WMI_REG_CHAN_LIST_CC_EXT_EVENTID.
