apalis-imx6: move to one overlay per accessory

Move the existing overlays to dtsi files and include them into one
accessory dts.
Provide data-mapping timings appropriately for each machine instead
of the hardcoding and use a single overlay per SoC to avoid code
duplication.

Set the bus-format via toradex specific data-mapping property in
the machine specifig overlay.

Make sure the panel-dpi compatible is set correctly in the display
specific overlay.

While at it use new lines consistently and set sensible width and
height dimension for a fullHD analog RGB monitor.
