media: i2c: ov9282: Correct the exposure offset
[ Upstream commitfeaf4154d6] The datasheet lists that "Maximum exposure time is frame length -25 row periods, where frame length is set by registers {0x380E, 0x380F}". However this driver had OV9282_EXPOSURE_OFFSET set to 12 which allowed that restriction to be violated, and would result in very under-exposed images. Correct the offset.
