Subject: [PATCH] drm/i915: PSR HSW: update after enabling sprite.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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.
