Instead of having each driver implement its own "is_this_yuv/rgb" function based on a restricted set of pixel value, it is better to do this in centralized manner. We therefore add a pix_enc member to the v4l2_format_info structure to quickly identify the related pixel encoding. And add helper function to find/check pixel encoding.
