ODROID-COMMON: media/vout: no use of 'vout=' for display resolution

Browse Source 
This patch is to disable kernel param 'vout=' completely and the set display
resolution with the given by 'hdmimode=' or 'cvbsmode' according to the cable
status. Since we are assuming that HDMI display is priority display device,
no matter CVBS cable is attached or HDMI cable is attached we select HDMI.
