videomode: create enum for videomode's display flags
Instead of having plain defines for the videomode's flags, add an enum for the flags. This makes the flags clearer to use, as the enum tells which values can be used with the flags field. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Steffen Trumtrar <s.trumtrar@pengutronix.de>
