914f896187 media: v4l: Fix missing tabular column hint for Y14P format
The original patch added two columns in the flat-table of Luma-Only
Image Formats, without updating hints to latex: above it.  This results
in wrong column count in the output of Sphinx's latex builder.

Fix it.

The Y10P, Y12P and Y14P format variants are packed according to
the RAW10, RAW12 and RAW14 formats as defined by the MIPI CSI-2
specification. Document it.

adb1d4655e media: v4l: Add V4L2-PIX-FMT-Y14P format
This is a packed grey-scale image format with a depth of 14 bits per
pixel. Every four consecutive samples are packed into seven bytes. Each
of the first four bytes contain the eight high order bits of the pixels,
and the three following bytes contains the six least significants bits
of each pixel, in the same order.

As the other formats only needed 5 bytes before, append two bytes in the
documentation array.

1810477630 media: v4l: Add V4L2-PIX-FMT-Y12P format
This is a packed grey-scale image format with a depth of 12 bits per
pixel. Two consecutive pixels are packed into 3 bytes. The first 2 bytes
contain the 8 high order bits of the pixels, and the 3rd byte contains
the 4 least significants bits of each pixel, in the same order.

Add the entry in userspace API, and document it.

b87f5e25b2 media: uapi: Add IPU3 packed Y10 format
Some platforms with an Intel IPU3 have an IR sensor producing 10 bit
greyscale format data that is transmitted over a CSI-2 bus to a CIO2
device - this packs the data into 32 bytes per 25 pixels. Add an entry
to the uAPI header defining that format.

This packed grey-scale image format has a depth of 10 bits per pixel.
Every four consecutive pixels are packed into 5 bytes. Each of the first
4 bytes contain the 8 high order bits of the pixels, and the 5th byte
contains the 2 least significants bits of each pixel, in the same order.

The first two bytes are not corresponding to this description, fix it.

af4f450576 media: doc: pixfmt-yuv: Move all luma-only YUV formats to common file
Luma-only pixel formats are documented in separate files. This
duplicates information, as those formats share comon traits. Consolidate
them in a single file and describe them in a single table.
