Subject: [PATCH 11/15] [media] Deprecate v4l2_mbus_pixelcode
The v4l2_mbus_pixelcode enum (or its values) should be replaced by the
media_bus_format enum.
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.
