[PATCH v2 1/2] dt-bindings: auxdisplay: adjust example indentation and use generic node names

From: Krzysztof Kozlowski
Date: Wed Feb 14 2024 - 10:55:07 EST

The example DTS should be indented with two or four (preferred) spaces,
as mentioned in Writing Schema document. While re-indenting, change the
node names to somehow generic names, as expected by Devicetree
specification.

Changes in v2:
1. Previous, removing GPIO expander node is gone, update GPIO expander
example as well: node name and indentation.
