[media] doc-rst: Unify documentation of the 8-bit bayer formats
The other raw bayer formats had a single sample depth dependent definition
whereas the 8-bit formats had one page for each. Unify the documentation
of the 8-bit formats.

Only one red, green or blue -value is given for each pixel. Missing components must be interpolated -from neighbouring pixels. From left to right the first row consists of a -red and green value, the second row of a green and blue value. This -scheme repeats to the right and down for every two columns and rows. +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...
