This is an SMMU for the adreno gpu, and adding this compatible lets
the driver use per-fd page tables, which are required for security
between GPU clients.

I see that other dtsi files use a bit different order for the
compatibility strings. They put "qcom,adreno-smmu" before
"arm,mmu-500". Can we please follow them?
With that fixed:
