[PATCH v3 2/7] media: dt-bindings: video-interface-devices: add video-interface-devices.h references

[Kieran Bingham]

Expand the documentation of the video-interface-devices orientation to
reference the include/dt-bindings/media/video-interface-devices.h header
which provides human readable defines for the orientation enum, to help
avoid hardcoding values in dts.
