[PATCH 2/3 v2] drm/panel: Add DT bindings for Novatek NT35510-based panels

[Linus Walleij]

This adds device tree bindings for the Novatek NT35510-based
family of panels. Since several such panels are in existence
we define bindings common for all, and define the compatible
string for one certain panel (Hydis HVA40WV1).

As other panels are discovered and investigated, we can add
more compatibles to the binding using oneOf constructions.

ChangeLog v1->v2:
- Rename file to novatek,nt35510,yaml to match the first
  compatible.
- Require both the specific display manufacturer compatible
  and the novatek,nt35510 compatible in strict sequence.
