[Impact]
On RKL platform with AMD RX540, system would hang during boot-up.

[Fix]
AMD introduce a brand new firmware, polaris 12 MC firmware.
This fix the issue and the system wouldn't hang during boot-up with AMD RX540.

[Test]
Verified on RKL platform and AMD RX540
System would boot-up and login to desktop successfully.

[Where problems could occur]
This's a brand new firmware to support Polaris-series,
it may introduce new issues.

Seems like the driver really shouldn't hang just because the firmware 
misbehaves.

Applied for both focal and hirsute, thanks. Impish got it via a new 
upstream snapshot.
