[PATCH] media: ov5640: Correct Bit Div register in clock tree diagram

[Paul Kocialkowski]

Although the code is correct and doing the right thing, the clock diagram
showed the wrong register for the bit divider, which had me doubting the
understanding of the tree. Fix this to avoid doubts in the future.

Thanks for spotting this! Correct indeed!

I'm not sure it's worth a fixes tag, but just in case:
Fixes: aa2882481cada ("media: ov5640: Adjust the clock based on the expected rate")
