WMI_REG_CHAN_LIST_CC_EVENTID also support 6 GHz, But it dose not support
6 GHz LPI, SP and VLP.
I did test with the board-2.bin/m3.bin/amss.bin(without regdb.bin) of this commit
https://github.com/kvalo/ath11k-firmware/commit/0b1d1b2e10f9839ee0675a2ac496bfeb87c304c1.
It only support country US. After added regdb.bin, it support many country.
So regdb.bin is needed now.
