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

(Rob) * Add Rob's R-b tag.
v3->v4: * Add type and descriptions for dual-lvds-{odd,even}-pixels properties. Also, update descriptions for port@0 and port@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.
