Add new functions for ath11k caldata: - ath11k_patch_mac (from 0 to 5) - ath11k_remove_regdomain - ath11k_set_macflag (some pre-caldata have the nvMacFlag flag unset which is needed to change the MAC address) Additionaly for ath10k caldata: - ath10k_remove_regdomain Signed-off-by: Paweł Owoc <frut3k7@gmail.com>
