drm/i915: PSR HSW: update after enabling sprite.

rodrigovivi · danvet · commit 642f9bb558de · 2014-06-13T17:45:28.000+02:00
On the current structure HSW doesn't support PSR with sprites enabled
but sprites can be enabled after PSR was enabled what would cause
user to miss screen updates.

v2: move it to update_plane.
