media: ov2680: Add a bunch of register tweaks

Usually when developing a sensor driver with help from the vendor
the vendor will provide a bunch of register tweaks for optimal
performance of the sensor.

The atomisp-ov2680.c driver was (presumably) developed by Intel with
help from OmniVision and indeed contains a bunch of register tweaks.

Add these register tweaks to the "main" ov2680.c driver.
