[PATCH v4 1/7] dt-bindings: media: Add macros for video interface devices

Add a new dt-bindings/media/video-interface-devices.h header that
defines macros corresponding to the orientation enumeration types from
media/video-interface-devices.yaml.

Expand the documentation of the video-interface-devices orientation to
reference the new header which provides human readable defines for the
orientation enum, to help avoid hardcoding values in dts.
