Dhinakaran Pandiyan 8cf6da7ef7 drm/i915/psr: Avoid DPCD reads when panel does not support PSR
Ville noticed that we are unncessarily reading DPCD's after knowing
panel did not support PSR. Looks like this check that was present
earlier got removed unintentionally, let's put it back.

While we do this, add the PSR version number in the debug print.
