ipa: rkisp1: awb: Expand comment
The RGB to YCbCr conversion matrix mentioned in a comment, coming from the hardware documentation, does not match any of the canonical matrices specified by any standard. While researching where the values came from, it became apparent they are likely Bt.601 limited range coefficients rounded to 6 bits of decimal precision. Record this in comments.
