overlays: apalis-imx6: fix lvds
The lt170410 panel uses single channel LVDS with 24bit color depth and spwg
color mapping.
Set the IPU's DI output to provide 24 bit color depth signals as the LDB
inputs need the same color depth at its input as it has to provide at its
LVDS output.
Set the LVDS data-width and color mapping explicitly in the overlay.
