media: i2c: ov01a10: Fix analogue gain range
[ Upstream commit 109e0feacaeca5ec2dd71d7d17c73232ce5cbddc ]
A analogue maximum gain of 0xffff / 65525 seems unlikely and testing
indeed shows that the gain control wraps-around at 16383, so set the
maximum gain to 0x3fff / 16383.
The minimum gain of 0x100 is correct. Setting bits 8-11 to 0x0 results
in the same gain values as setting these bits to 0x1, with bits 0-7
still increasing the gain when going from 0x000 - 0x0ff in the exact
same range as when going from 0x100 - 0x1ff.
