iommu/arm-smmu-qcom: Add glymur MDSS to ACTLR client table
Add qcom,glymur-mdss to the qcom_smmu_actlr_client_of_match[]
table to configure the SMMU-500 context bank for the display
subsystem (MDSS) on the Glymur platform.
The settings disable the next-page prefetcher while keeping
macro TLB caching enabled. Without this entry,
qcom_smmu_set_actlr_dev() finds no match for the glymur MDSS
device and leaves the context bank ACTLR at its reset value.
