[Freedreno] [PATCH] drm/msm/dpu: Add missing safe_lut_tbl in sc8180x catalog

[Bjorn Andersson]

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.
