[PATCH v2 2/3] mt76: mt7921: add mt7921_mcu_sta_update support

[sean.wang at mediatek.com]

From: Sean Wang <sean.wang at mediatek.com>

Add mt7921_mcu_sta_update support to make we are able to update the station
record with the current state the station has into the mt7921 firmware at
runtime. That is the prerequisite patch to fix .sta_state incorrect
implementation for the mt7921 driver.
