media: doc: pixfmt-yuv: Move all planar YUV formats to common file
Planar pixel formats are documented in separate files. This duplicates
information, as those formats share comon traits. Consolidate them in a
single file and summarize their descriptions in a single table.

The three -components are separated into three sub-images or planes. The Y plane is -first. The Y plane has one byte per pixel.

Each Cr -belongs to 16 pixels, a four-by-four square of the image. Following the -Cr plane is the Cb plane, just like the Cr plane. -``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first, -then the Cr plane. - -If the Y plane has pad bytes after each row, then the Cr and Cb planes -have ¼ as many pad bytes after their rows.
