[PATCH v3 14/16] drm/gma500: Stop using mode->private_flags

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

gma500 only uses mode->private_flags to convey the sdvo pixel
multiplier from the encoder .mode_fixup() hook to the encoder
.mode_set() hook. Those always seems get called as a pair so
let's just stuff the pixel multiplier into the encoder itself
as there are no state objects we could use in this non-atomic
driver.

Paves the way for nuking mode->private_flag.
