dt-bindings: auxdisplay: ht16k33: Convert to json-schema
Convert the Holtek HT16K33 LED controller with keyscan Device Tree
binding documentation to json-schema.
Move the file from display to auxdisplay.
Update the example:
- Sort properties in order of documentation,
- Group tuples using angle brackets to improve human readability and
enable automatic validation.
