ENGR00174911 MX6x Setting HDMI default mode according bootload cmdline
Origin HDMI default video mode is setting to VGA.
But the HDMI will change to the vide mode setting in bootloader
command line when the first time HDMI cable plugin.
It will cause GUI sometime can't not get correct FB video mode
when system bootup without HDMI cable plugout.
