[amd-staging-drm-next] regression - no fan info (sensors) on RX580

[Dieter Nützel]

Hello all,

since latest update

1d7da702e70d3c27408a3bb312c71d6be9f7bebe
drm/amd/powerplay: fix spelling mistake: "dividable" -> "divisible"

I didn't get fan info with my RX580 (Polaris21) any longer.

Worked with this commit:

786df0b89fe5a0b405d4de0a1ce03003c0743ec3
drm/amd/display: fix pflip irq registor for raven

Sorry, I do not have full time for bisect, because we are on way to our 
vacation.

Maybe in the evening (only a few commits).

Greetings,
Dieter
