[PATCH 2/6] drm/exynos: don't do any DPMS operation while updating planes

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan at collabora.co.uk>

DPMS only makes sense when the mode changes, for plane update changes do
not perform any dpms operation.

This move places the win_commit() and commit() calls directly in the code
instead of calling exynos_drm_crtc_commit() thus avoiding DPMS operations.
