Repeated comment from v2 feedback:

Please send a patch to:

Documentation/devicetree/bindings/iommu/arm,smmu.yaml

...adding 'qcom,sc7180-smmu-v2'.  If you do this it will point out
that you've added a new clock: "mem_iface_clk".  Is this truly a new
clock in sc7180 compared to previous IOMMUs?  ...or is it not really
needed?

As per continued comments on v2, please see if this works for you:

  power-domains = <&gpucc CX_GDSC>, <0>;
  power-domain-names = "cx", "gx";

...and work to get something more real for "gx" ASAP.  It did seem to
boot for me and (unless someone disagrees) it seems better than
totally leaving it out / violating the bindings?

I can confirm that this clock is needed for SC7180. I will send out a 
new patch
to update the documentation this week.
