Correctly handle Exposure mode control: The value definition for the V4L2 interface for exposure mode control does not map directly to the UVC control interface. Add some conversion and configuration fixes. Enable AWB control: This is a bit of a hack. The RaspberryPi V4L2 driver exposes only a menu of pre-defined color temperatures and two of those are manual and auto. This control definition does not have any corresponding equivalent in the UVC specification. Override the UVC color temperature control interface to map directly to the V4L2 AWB interface. This will allow controlling the AWB modes from the host but will only show number values with no explanation of what the numbers refer to. 0: Manual 1: Auto 2: Incandescent 3: Fluorescent 4: Fluorescent H 5: Horizon 6: Daylight 7: Flash 8: Cloudy 9: Shade This has been tested only on RaspberryPi 4B HW with the 8 Mpixel v2 camera.
