libipa: camera_sensor_helper: Add OV5675 black level
Add black level value for OV5675 camera sensor. According to datasheet, default value is 0x10, 10 bits width. However, Linux kernel driver initializes black level target value to 0x40. Set the value to the same as in kernel driver, but scaled to 16 bits.
