Keep this enum in v4l2-mediabus.h and create a new header containing the v4l2_mbus_framefmt struct definition (which is not deprecated) so that we can add a #warning statement in v4l2-mediabus.h and hopefully encourage users to move to the new definitions. Replace inclusion of v4l2-mediabus.h with v4l2-mbus.h in all common headers and update the documentation Makefile to parse v4l2-mbus.h instead of v4l2-mediabus.h.
