dt-bindings: lcdif: Add endpoint bus-width property

The DPI output of the LCD interface can be configured with a bus width
of 16, 18, or 24 bits. Introduce a bus-width property to the output
endpoint, specifying the number of parallel RGB bits connected.

[Severity: Low]
Will this schema validate device trees with multiple endpoints correctly?

Defining `endpoint:` under `properties` will only match nodes exactly named
"endpoint". Any numbered endpoints like "endpoint@1" or "endpoint@2" will
silently bypass these constraints and the `unevaluatedProperties: false`
check.

Should this be defined using `patternProperties: "^endpoint(@[0-9a-f]+)?$":`
instead to ensure the rules apply to all endpoint nodes?
