[Intel-gfx] [PATCH 00/11] Enable PSR on Haswell.

[Rodrigo Vivi]

I'm resending full series again because after accepting most of suggestions
and rebasing again on drm-intel-nightly most of patches got some kind of
conflict so the full series is here again.

First 3 patches on this series are already reviewed and I'd be glad if they
were merged asap to avoid future conflicts. This patches at least allows
people to know if they have psr panel or not.

For the rest I accepted most of suggestions and explained on previous emails
the ones I didn't accepted and why. However even the ones I didn't accepted
I tested and verified that they caused some kind of issue.

This version is working very fine for a long time in my machine. I'd appreciate if you could merge everything since now psr is disabled by default by kernel flag. So I'm 100% sure that this series won't cause any kind of regression for any user.

I understand that it would be good to deliver psr enabled by default however I'm changing this default behaviour because I'm sure that PSR will cause regression without userspace (DDX) help when using kde and xdm.

Thanks in advance,
Rodrigo.
