Document S_ROUTING behaviour for different devices.

Generally in devices that produce streams the streams are static and some
can be enabled and disabled, whereas in devices that just transport them
or write them to memory, more configurability is allowed. Document this.

media: Documentation: Additional streams generally don't harm capture

Having extra streams on the source end of the link that cannot be captured
by the sink sub-device generally are not an issue, at least not on CSI-2
bus. Still document that there may be hardware-specific limitations. For
example on parallel bus this might not work on all cases.

media: uapi: v4l: Add generic 8-bit metadata format definitions

Generic 8-bit metadata formats define the in-memory data layout but not
the format of the data itself. The reasoning for having such formats is to
allow CSI-2 receiver drivers to receive and DMA drivers to write the data
to memory without knowing a large number of device-specific formats.

These formats may be used only in conjunction with a Media Controller
pipeline where the internal pad of the source sub-device defines the
specific format of the data (using an mbus code).

media: Documentation: Update documentation for streams

Document how streams interacts with formats and selections.

Update documentation in respect to what is allowed, in particular streams
are only supported via full routes, source-only routes are not supported
right now.

The centerpiece of the API additions are streams. Albeit routes are
configured via S_ROUTING IOCTL that also declares streams, it is streams
that are accessed through other APIs. Thus refer to streams instead of
routes in documentation.

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.
