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.

Changes since v1:
- Dual-license under GPL-2.0-only or MIT
- Rename PARALLEL TO BT601
Contrary to popular belief, further investigation revealed that BT.601 doesn't define VSYNC and HSYNC (or HREF, as it is also commonly called) signals. MEDIA_BUS_TYPE_BT601 is thus likely not a good name. I haven't been able to find a standard for parallel camera interfaces that would be a good match here. On the display side there's MIPI DPI, but on the camera side it seems things have evolved quite organically. I may have missed something though.
So keep 'PARALLEL' and anything less ambiguous will be a new type.
