dt-bindings: fix references to files converted to yaml

There were several files converted to yaml, but the .txt file
is still referenced somewhere else.

Update the references for them to point to the right file.

drm/tilcdc: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

dt-bindings: remove 'interrupt-parent' from bindings

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

drm/tilcdc: add a da850-specific compatible string

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.

drm/tilcdc: Remove "default" from blue-and-red-wiring property binding

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

drm/tilcdc: Add blue-and-red-crossed devicetree property

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.

dt-bindings: consolidate display related bindings

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.
