Video node formats have direct dependency by the sub-device pad formats. Remove dependency for SoC version and move format definitions in device which creates video node. This commit attaches a struct to the VFE resources that holds format description, so it is much easier to assign them to the video node. No need to use a switch-case. NOTE: The mbus_bpp is used to calculate the clock rates and is different from bpp which is the bits per pixel written to memory. We need to keep both values to not break the calcualtions.
