Add RCar DU kms lib support for sharing the common code between RCar and RZ/G2L DU KMS drivers by moving rcar_du_format_infos table and rcar_du_format_infos() to the lib file. Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx> --- v6->v7: * Rebased to drm-tip. v1->v6: * Rebased on drm-misc-next and DU-next. v1: * Created the lib suggested by Laurent.
