[PATCH v4] dt-bindings: display: panel: one file of all simple LVDS panels with dual ports

To complement panel-simple.yaml, create panel-simple-lvds-dual-ports.yaml.
panel-simple-lvds-dual-ports.yaml is for all simple LVDS panels that
have dual LVDS ports and require only a single power-supply.
The first port receives odd pixels, and the second port receives even pixels.
Optionally, a backlight and an enable GPIO can be specified as properties.
Panels with swapped pixel order, if any, need dedicated bindings.
Migrate 'auo,g133han01', 'auo,g185han01', 'auo,g190ean01',
'koe,tx26d202vm0bwa' and 'nlt,nl192108ac18-02d' over to the new file.
The objectives with one file for all the simple LVDS panels with dual ports are:
- Make it simpler to add bindings for this kind of LVDS panels
- Keep the number of bindings file lower
- Keep the binding documentation for this kind of LVDS panels more consistent
- Make it possible for drivers to get pixel order via
drm_of_lvds_get_dual_link_pixel_order(), as the optional 'ports' property is
allowed

v3->v4:
* Add type and descriptions for dual-lvds-{odd,even}-pixels properties.
Also, update descriptions for port at 0 and port at 1 properties accordingly. (Rob)
v2->v3:
* Do not allow 'port' property. (Rob)
* Define port number. (Rob)
* Specify 'dual-lvds-odd-pixels' and 'dual-lvds-even-pixels' properties. (Rob)
v1->v2:
* Correct pixel order in example LVDS panel node.

+description: |
+ This binding file is a collection of the LVDS panels that
+ has dual LVDS ports and requires only a single power-supply.
+ The first port receives odd pixels, and the second port receives even pixels.
+ There are optionally a backlight and an enable GPIO.
+ The panel may use an OF graph binding for the association to the display,
+ or it may be a direct child node of the display.
+
+ If the panel is more advanced a dedicated binding file is required.
