dt-bindings: auxdisplay: adjust example indentation and use generic node names

Browse Source 
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.
