[media] Move mediabus format definition to a more standard place

Define MEDIA_BUS_FMT macros (re-using the values defined in the
v4l2_mbus_pixelcode enum) into a separate header file so that they can be
used from the DRM/KMS subsystem without any reference to the V4L2
subsystem.

Then set V4L2_MBUS_FMT definitions to the MEDIA_BUS_FMT values using the
V4L2_MBUS_FROM_MEDIA_BUS_FMT macro.

-/*
- * These pixel codes uniquely identify data formats on the media bus. Mostly
- * they correspond to similarly named V4L2_PIX_FMT_* formats, format 0 is
- * reserved, V4L2_MBUS_FMT_FIXED shall be used by host-client pairs, where the
- * data format is fixed. Additionally, "2X8" means that one pixel is transferred
- * in two 8-bit samples, "BE" or "LE" specify in which order those samples are
- * transferred over the bus: "LE" means that the least significant bits are
- * transferred first, "BE" means that the most significant bits are transferred
- * first, and "PADHI" and "PADLO" define which bits - low or high, in the
- * incomplete high byte, are filled with padding bits.
- *
- * The pixel codes are grouped by type, bus_width, bits per component, samples
- * per pixel and order of subsamples. Numerical values are sorted using generic
- * numerical sort order (8 thus comes before 10).
- *
- * As their value can't change when a new pixel code is inserted in the
- * enumeration, the pixel codes are explicitly given a numerical value. The next
- * free values for each category are listed below, update them when inserting
- * new pixel codes.
