Due to some potential tweaks for the da850 LCDC (for example: the
required memory bandwith settings) we need a separate compatible
for the IP present on the da850 boards.

Remove "default" keyword from blue-and-red-wiring devicetree property
binding document. The code does not support and there is no intention
to support it.

Add "blue-and-red-wiring"-device tree property and update devicetree
binding document.
The red and blue components are reversed between 24 and 16 bit modes
on am335x LCDC output pins. To get 24 RGB format the red and blue
wires has to be crossed and this in turn causes 16 colors output to be
in BGR format. With straight wiring the 16 color is RGB and 24 bit is
BGR.
The new property describes whether the red and blue wires are crossed
or not. If the property is not present or its value is not recognized
the legacy mode is assumed. The legacy configuration supports RGB565,
RGB888 and XRGB8888 formats. However, depending on wiring, the red and
blue colors are swapped in either 16 or 24-bit color modes.
For more details see section 3.1.1 in AM335x Silicon Errata:

The legacy panel.txt and tfp410.txt bindings are still the only supported
way to connect lcd panel and tfp410 DVI encoder to tilcdc.

This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
