[Intel-gfx] [PATCH 2/2] drm/i915/psr: Move hsw_enable_source after enabling sink.

[Rodrigo Vivi]

No functional change is expected here since at this point
PSR is not allowed to go to any active state. In other
words, not really enabled.

However let's do in a separated patch so it gets clear
on what is change and specially it can helps on bisect
case if we figure something has caused changes in behaviour.

But this needs to be done before we make the vfunc to
enable source to be in parity with VLV implementation.
