[PATCH v4 1/4] dt-bindings: lcdif: Add endpoint bus-width property

[Francesco Dolcini <francesco@dolcini.it>]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

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.

v4: use /schemas/graph.yaml#/$defs/port-base
v3: use video-interfaces.yaml
v2: use the common bus-width property instead of the legacy interface-pix-fmt
