ipa: rkisp1: Move ov4689 and ov5640 black levels into sensor helpers
Move black levels for tuning files that contained a BLC block into
the camera sensor helpers.
ov4689.yaml had 66@12bit while the datasheet states 64@12bit. Use the
value from the datasheet (scaled to 16bit).
ov5640.yaml had 256@12bit while the datasheet states 16@10bit. Looking
at the commit message the 256 most likely stems from the imx219 tuning
file and 16@10bit is the same as the 64@12bit from the ov4689. This
seems more likely and is therefore used.
