[PATCH RFC v2 1/5] dt-bindings: display: panel: Fix port binding

[Kory Maincent]

Faced a binding error check while adding the data-lanes property in the
ilitek,ili9881c binding. See the next patch for the binding changes.
Here is the error:
Documentation/devicetree/bindings/display/panel/ilitek,ili9881c.example.dtb:
panel at 0: port:endpoint: Unevaluated properties are not allowed
('data-lanes' was unexpected)

Change the reference of properties/port to $defs/port-base to makes it
work.
The only difference between port and port-base is the unevaluatedProperty
set to false. I have tried to use properties/port in both panel-common
and ilitek,ili9881c bindings but the error is still there. The only way
to not face the error is to use $defs/port-base reference. I don't
really understand the ins and outs, maybe it is a issue from the binding
check tool.
