Subject: [PATCH v2 02/11] dt-bindings: display: panel: ronbo,rb070d30:
 panel-common ref

Add missing ref on panel-common.yaml for this dsi panel so that common
properties can be shared.

Drop reset-gpios and backlight as they are already in panel-common.

Switch from additionalProperties to unevaluatedProperties so that common
panel properties are available without repeating them in this binding.

Notably panel-common defines the "port" property for linking panels to a
source - which was missing from this panel. Mark it as required.
