Although there isn't any harm in clearing them. The need to clear them out here should never arrive. When applying configurations for a manual update manager, we never do any register writes, i.e, calls to dss_mgr_write_regs and dss_mgr_write_regs_extra never happen while applying. We do all these writes only when we call dss_mgr_start_update. Hence, there is never a time when the shadow registers are dirty. Remove the call to mg_clear_shadow_dirty.
