Krzysztof Kozlowski 72cfe73347 dt-bindings: display: panel: Drop redundant properties
The purpose of common schemas, like panel-common.yaml, is to list
applicable properties.  It can list common ABI, e.g. "label" property,
and pure hardware related properties like power supply or GPIOs.  In the
second case it means that all panels have these supplies or GPIOs.
This is the only meaning when hardware property is allowed in common
schema, because bindings are precise and we do not define common schemas
for "possible" hardware configurations.

Following this, all panel bindings which reference common schema and use
"unevaluatedProperties: false" do not need to list these common parts.

Simplify such bindings to also reduce copy-paste code and review time
for new contributions.
