Laurent Pinchart c2b66cafdf [media] v4l: doc: Remove row numbers from tables
Shorten the tables by removing row numbers in comments, allowing for
later insertion of rows with minimal diffs.

All changes have been generated by the following script.

8-bit Bayer formats
Description
===========
These four pixel formats are raw sRGB / Bayer formats with 8 bits per
sample. Each sample is stored in a byte. Each n-pixel row contains n/2
green samples and n/2 blue or red samples, with alternating red and
blue rows. 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.
