[Intel-gfx] [PATCH 10/10] drm/i915: Enable PSR for Baytrail and Braswell.

[Rodrigo Vivi]

This patch is the last in series of VLV/CHV PSR,
that finnaly enable psr by adding it to HAS_PSR
and calling the propper enable and disable
functions on the right places.

Although it is still disabled by default.
