[Impact]
Intel AX201 firmware crashes or hardware RX ring buffer hangs after S3.

[Fix]
Use new firmware from linux-firmware.git can solve the issue.

[Test]
WiFi works for each cycle of 1000 S3 cycles.

[Regression Potential]
Both Focal 5.4 and OEM 5.6 kernel use this firmware, so it might regress
current 5.4 users. I did a smoke test with this firmware on Focal 5.4,
and I didn't see any regression.

Instead of cherry-pick the commit, only add the firmware needed for
AX201 to minimize the regression risk.

Applied, thanks!
