Why is this being moved? Not sure what the differences between the 2 
bindings, but doesn't seem like a backwards compatible change.

Hmm. I followed the existing schemas, but they are incorrect. It looks
like the commit 724fabf5df13 ("dt-bindings: phy: qcom,qmp-usb3-dp: Add
DP phy information") has introduced backwards-incompatible change,
which is not followed by the current kernel device trees. I'd proposed
to move qcom,sc7180-qmp-usb3-phy and qcom,sdm845-qmp-usb3-phy back to
bindings/phy/qcom,qmp-phy.yaml (as those device nodes do not use DP
serdes block, etc).

I'll include the fix into v4 of this series.
