The values of these parameters will be different for differnet panel based on dsi rate, lane count, etc. Remove the hardcodings and make these as parameters whch will be initialized in panel specific sub-encoder implementaion. This will also form groundwork for planned generic panel sub-encoder implemntation based on VBT design enhancments to support multiple panels v2: Mask away the port_bits before use Signed-off-by: Shobhit Kumar <shobhit.kumar@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
