drm/dsc: Modify DRM helper to return complete DSC color depth capabilities
DSC DPCD color depth register advertises its color depth capabilities
by setting each of the bits that corresponding to a specific color
depth. This patch defines those specific color depths and adds
a helper to return an array of color depth capabilities.
