Document V4L2_PIX_FMT_MT2110T and V4L2_PIX_FMT_MT2110R. These two
formats are nearly identical, reusing MM21 format and expending it
by inserting chunk of 16 bytes of lower 2 bit pixel data after each
chunk of 64 bytes higher 8 bit of data.

This introduces support for the Aspeed JPEG format, where the new frame
can refer to previous frame to reduce the amount of compressed data.
The concept is similar to I/P frame of video compression. It will
compare the new frame with previous one to decide which macroblock's
data is changed, and only the changed macroblocks will be compressed.
This Aspeed JPEG format is used by the video engine on Aspeed platforms,
which is generally adapted for remote KVM.

MM21 has been documented through two software implementation [0] in libyuv
and [2] GStreamer. This format is similar to other tiled format, though it
uses uneven tile sizes. The luma tiles are 16x32 while the chroma tile have
a subsampled size of 16x16. This is the uncompressed cousin of
V4L2_PIX_FMT_MT21C and shares its tiling pattern and alignment.

Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee38 ("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.
