[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. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

-Bayer RGB format
+8-bit Bayer formats
Description
===========
-This is commonly the native format of digital cameras, reflecting the
-arrangement of sensors on the CCD device. 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... GBGB..., etc. Below is an example of one of these formats:
