OMAP: DSS2: move update() and sync()
Move update() and sync() from omap_dss_device to omap_dss_driver. Also, update was hardcoded to use virtual channel 0. This patch adds a parameter that specifies the VC. This is part of a larger patch-set, which moves the control from omapdss driver to the display driver. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
