media: dt-bindings: media: Add macros for video interface bus types

Add a new dt-bindings/media/video-interfaces.h header that defines
macros corresponding to the bus types from media/video-interfaces.yaml.
This allows avoiding hardcoded constants in device tree sources.

Based on linux commit f7eeb0084593 ("media: dt-bindings: media: Add macros
for video interface bus types")
