[PATCH 4/6] wifi: mt76: mt7921: get regulatory information from the clc event

From: Ming Yen Hsieh <mingyen.hsieh at mediatek.com>
The clc event can report the radio configuration for the corresponding
country and the driver would take it as regulatory information of a
certain platform device.
This patch would change the clc commnad from no-waiting to waiting for
event. For backward compatible, we also add a new nic capability tag
to indicate the firmware did support this new clc event from now on.
