arm: mx6: cm-fx6: map HDMI to IPU1 DI0 explicitly
U-Boot does not explicitly assign the display to an IPU interface. Instead, it
relies on the power-on default of DI0.
Since the kernel reassigns HDMI display to DI1, after a warm reset the HDMI
display no longer works in U-Boot.
Fix this by explicitly assigning HDMI to IPU1 DI0 in U-Boot.
