I have no objection to ${SUBJECT} change landing and based on all your
research and Alex's review/testing I think it's good to go.

However, now that you're removed the driver that cared about
"qcom,sc7180-ipa-virt", should we also be removing it from the
`bindings/interconnect/qcom,rpmh.yaml` file and the `sc7180.dtsi`
file? I think that removing it from _either_ the driver (like your
patch here does) _or_ the sc7180.dtsi file would fix the bug, right?
...and then removing it from the yaml would just be cleanup...
