[PATCHv2 25/45] drm: omapdrm: Move plane info and win out of the plane structure

[Tomi Valkeinen]

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

The plane info and win structures are only used to setup the plane
through the DSS API. Move them from the plane structure to local
variables in omap_plane_setup().
