Update the register 0x3503 to use 'no delay latch' for gain.
This makes sensor to output the first frame as normal rather
than a very dark one.

Without CONFIG_PM, we get a harmless build warning:
drivers/media/i2c/ov2685.c:516:12: error: 'ov2685_runtime_suspend' defined but not used [-Werror=unused-function]

This marks the affected functions as __maybe_unused.

Assign ret in the default case for s_ctrl callback. This can't happen but
still may result in compiler warnings.

This patch adds driver for Omnivision's ov2685 sensor.
Though the ov2685 can output yuv data, this driver only
supports the raw bayer format, including the following features:
- output 1600x1200 at 30fps
- test patterns
- manual exposure/gain control
- vblank and hblank
- media controller
- runtime pm
