iommu/arm-smmu-qcom: Restore ACTLR settings for MDSS on sa8775p
The ACTLR configuration for the sa8775p MDSS client was inadvertently
dropped while reworking the commit f91879fdf70b ("iommu/arm-smmu-qcom:
Add actlr settings for mdss on Qualcomm platforms"). Without this
entry, the sa8775p MDSS block does not receive the intended default
ACTLR configuration.
Restore the missing compatible entry so that the platform receives the
expected behavior.
Fixes: f91879fdf70b ("iommu/arm-smmu-qcom: Add actlr settings for mdss on Qualcomm platforms")
