drm/i915: Enable PSR for Baytrail and Braswell.
This patch is the last in series of VLV/CHV PSR,
that finally enable PSR by adding it to HAS_PSR
and calling the proper enable and disable
functions on the right places.
Although it is still disabled by default.
v2: Rebase over intel_psr and merge Durgadoss's fixes.
v3: Fix typo.
