[PATCH v6 47/84] drm/omap: simplify DSI manual update code

[Tomi Valkeinen <tomi.valkeinen@xxxxxx>]

From: Sebastian Reichel <sebastian.reichel@xxxxxxxxxxxxx>

Move dsi_ops into the main structure, since all other ops
are gone. Instead of checking the device type we can simply
check if dsi_ops are set.
