libcamera: v4l2_device: Adjust colorspace based on pixel format
V4L2 has no "none" YCbCr encoding, and thus reports an encoding for all formats, including RGB and raw formats. This causes the libcamera ColorSpace to report incorrect encodings for non-YUV formats. Fix it by overriding the encoding reported by the kernel to YCbCrEncoding::None for non-YUV pixel formats and media bus formats. Similarly, override the quantization range of non-YUV formats to full range, as limited range isn't used for RGB and raw formats.
