commita37a512db3upstream. Legacy Display Unit (LDU) fb dirty support used a custom fb dirty callback. Latter handled only the DIRTYFB IOCTL presentation path but not the ADDFB2/PAGE_FLIP/RMFB IOCTL path, common for Wayland compositors. Get rid of the custom callback in favor of drm_atomic_helper_dirtyfb and unify the handling of the presentation paths inside of vmw_ldu_primary_plane_atomic_update. This also homogenizes the fb dirty callbacks across all DUs: LDU, SOU and STDU.
