Bug description:
[Impact]
When doing suspend test, the system will fail to be suspended since the MT7925 controller couldn't be suspended. The root cause is caused by the command timeout issued from mt7925 driver.

[Fix]
Cherry-pick the following two patches from linux-next:

1b97fc8443ae wifi: mt76: mt7925: fix the unfinished command of regd_notifier before suspend
8f6571ad470f wifi: mt76: mt7925: add handler to hif suspend/resume event

Also, cherry-pick the following commit from linux-firmware:

62ee1c4b2d35 linux-firmware: update firmware for MT7925 WiFi device

[Test Plan]
1. Install Ubuntu image and boot into the OS
2. Run the suspend test by $ fwts s3 --s3-device-check --s3-device-check-delay=60 --s3-multiple=1 --s3-sleep-delay=60, and see if the error occurred.

[Where problems could occur]
Due to the new FW, there might be a unexpected behavior of the MT7925 hardware.
