wifi: ath12k: store and send country code to firmware after recovery

Currently ath12k does not send the country code to firmware after device
recovery. As a result the country code will be the default one which
is reported from firmware. Country code is important, so ath12k also
need to restore it to the value which was used before recovery.

This is only needed for platforms which support the current_cc_support
hardware parameter.
