ENGR00299600 hdmi:yocto gui can not show to some TV on ard board

For i.MX6 ARD board, the board not support read EDID from TV,
so HDMI driver will create a default support mode list when system
bootup.
Because yocto xserver can not get video mode information from
framebuffer now, and xserver will set default video mode XGA
to framebuffer, but XGA mode is not support by hdmi.

Remove XGA and SXGA from default support list.
HDMI driver will find a nearest match video mode in support list.
It is VGA mode. HDMI support VGA mode well.
Issue is fixed.
