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 'ports' property is required
