The Renesas Camera Receiver Unit in the RZ/V2H SoC can output RAW
data captured from an image sensor without conversion to an RGB/YUV
format. In that case the data are packed into 64-bit blocks, with a
variable amount of padding in the most significant bits depending on
the bitdepth of the data. Add new V4L2 pixel format codes for the new
formats, along with documentation to describe them.

Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee3862 ("docs: Create a user-space API guide").
As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.
Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.
