ipa: rpi: alsc: Do not allow zero colour ratio statistics
The algorithm computes R/G and B/G colour ratio statistics which we should not allow to go to zero because there is clearly no gain you could apply to R or B to equalise them. Instead flag such regions as having "insufficient data" in the normal manner.
