i.MX6: nitrogen6x: force HDMI onto IPU0/DI0

Browse source 
Our Linux kernel switches the HDMI connector onto IPU0/DI1,
but the U-Boot display driver only supports IPU0/DI0 for the
time being.

Because of this, a soft re-boot will leave the HDMI output
connected to the wrong display port and prevent video from
being displayed.
