As per prior discussion "qcom,sc7180-smmu-v2" needs to be added to the bindings.

As per discussion in v3 [1], "mem_iface_clk" is new and needs to be
added to the bindings. Presumably that patch should be posted / Acked
by Rob before we land this dts.
Other than relying on un-posted bindings, this looks sane to me and
this patch lets me bring the GPU up on my sc7180-based board.
