Bluetooth: btmtksdio: fix the reset takes too long

2022-05-13T11:19:01Z

Sending WMT command during the reset in progress is invalid and would get no response from firmware until the reset is complete, so we ignore the WMT command here to resolve the issue which causes the whole reset process taking too long.

Bluetooth: btmtksdio: fix possible FW initialization failure

2022-05-13T11:18:17Z

According to FW advised sequence, mt7921s need to re-acquire privilege immediately after the firmware download is complete before normal running. Otherwise, it is still possible the bus may be stuck in an abnormal status that causes FW initialization failure in the current driver.
