media: docs: move uAPI book to userspace-api/media

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.

+10-bit Bayer formats expanded to 16 bits
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 10 bits per
+sample. Each sample is stored in a 16-bit word, with 6 unused
+high bits filled with zeros. Each n-pixel row contains n/2 green samples and
+n/2 blue or red samples, with alternating red and blue rows. Bytes are
+stored in memory in little endian order. They are conventionally described
+as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of
+these formats:
+
+**Byte Order.**
+Each cell is one byte, the 6 most significant bits in the high bytes
+are 0.
