ENGR00289053-2 MX6 SabreSD: Disable HDMI detect
As the HDMI splash screen feature is not well supported,
we should not set it to be the default display. In case,
users leave the 'panel' uboot environment variable empty
and connect the board with a HDMI monitor, the HDMI detect
funtion will work and enable the HDMI splash screen. So,
this patch disables HDMI detect function so that users
may only explicitly set the 'panel' variable to be 'HDMI'
to use HDMI splash screen.
