Add safe lut configuration for all the targets in dpu
driver as per QOS recommendation.
Issue reported on SC7280:
With wait-for-safe feature in smmu enabled, RT client
buffer levels are checked to be safe before smmu invalidation.
Since display was always set to unsafe it was delaying the
invalidaiton process thus impacting the performance on NRT clients
such as eMMC and NVMe.
Validated this change on SC7280, With this change eMMC performance
has improved significantly.
Changes in v1:
- Add fixes tag (Sai)
- CC stable kernel (Dimtry)
Fixes: cfacf946a464d4(drm/msm/disp/dpu1: add support for display for
