The \endgroup command at the bottom of a table added in commit
5374d8fb75 ("media: Add P010 video format") doesn't have a
corresponding \begingroup command preceding it.
This imbalance causes an build error in "make pdfdocs".
Fix the issue by removing it.

Two labels used _ instead of - so were never found and one new PIX_FMT was
missing the label altogether. This led to these warnings:

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.

Add more information about V4L2_PIX_FMT_NV12MT and
V4L2_PIX_FMT_NV12M_16X16, so it's clearer for driver authors and users.
Also, group the two pixel formats with the other tiled formats,
for clarity.
Unlike the recently introduced tiled formats (V4L2_PIX_FMT_NV12_4L4, etc)
these formats have remained Samsung-specific until now. Therefore, and
although the NV12MT and NV12MT_16X16 nomenclatures are less clear, we are
keeping them as-is.

This format is produced by VeriSilicon Hantro G2 and VC8000D cores.
It is a simple 4x4 tiling layout in a linear way.
The pixel format was introduced by GStreamer using FourCC VT12,
so let's stick to it.

The V4L2_PIX_FMT_HM12 format is actually a simple NV12 tiled format,
with 16x16 linear tiles. Rename the format and move its documentation
together with the other tiled NV12 formats.
Keep V4L2_PIX_FMT_HM12 for application compatibility.

Add missing format macros for the tables there to be properly
output.
While here, also remove the empty ".. note::" markup.
It should be noticed that ".. [1]" markups will generate footnotes,
and not a note within the main text body.
