rk3288: Set HDMI display mode to 480p

Browse source 
If an HDMI display is detected (EDID can be read), set the
display mode to 480p. If for some reason 480p is not supported
then we'll fall back to the automatically detected display mode.

BUG=chrome-os-partner:42946
BRANCH=firmware-veyron
TEST=dev mode screen shows up on Mickey at 480p resolution
