[PATCHv2 19/45] drm: omapdrm: Switch connector DPMS to atomic helpers

[Tomi Valkeinen]

From: Laurent Pinchart <laurent.pinchart at ideasonboard.com>

The atomic connector DPMS helper implements the connector DPMS operation
using atomic commit, removing the need for DPMS helper operations on
CRTCs and encoders.
