iommu/arm-smmu-qcom: Add actlr settings for mdss on Qualcomm platforms

Browse source 
Add ACTLR settings for missing MDSS devices on Qualcomm platforms.

These are QoS settings and are specific to per SoC thus different
settings, eg: some have shallow prefetch while others have no
prefetch.

Aswell, this prefetch feature is not implemented for all the
platforms, capturing to those are implemented to the best of my
knowledge.
