[SRU Justification]
[Impact]
Few recent AMD systems shows "snd_hda_intel 0000:00:1f.3: azx_get_response
timeout" and fail to detect the HDMI/DP audio output device when connects to
external monitor. It will work magically when re-loading the driver.
[Fix]
Backport the upstream fix c0f1886de7e1 ("Allow repeatedly probing on codec
configuration errors) from 5.15.0 rc. It adds the capability for retrying the
probe upon codec probe errors on the certain AMD platforms.
[Test]
1. Connect the external monitor to particular affected AMD systems with HDMI
or DisplayPort.
2. Go to Audio Settings to check if the HDMI/DP audio output device exist or
not.
[Where problems could occur]
Should be low risk, it adds the chance for retrying codec probe and won't
affect machines which used to work.

3) connect an external monitor via DP Port
4) check sound setting --> Output Device
5) switch to performance mode
6) check sound setting --> Output Device
[Expected result]
