    drm/msm/dpu: Add missing safe_lut_tbl in sc8180x catalog
    
    [ Upstream commit 7cc2621f16b644bb7af37987cb471311641a9e56 ]
    
    Similar to SC8280XP, the misconfigured SAFE logic causes rather
    significant delays in __arm_smmu_tlb_sync(), resulting in poor
    performance for things such as USB.
    
    Introduce appropriate SAFE values for SC8180X to correct this.
