Migrate legacy bindings (described in qcom,sc7180-qmp-usb3-dp-phy.yaml)
to qcom,sc8280xp-qmp-usb43dp-phy.yaml. This removes a need to declare
the child PHY node or split resource regions.

Thank you for your patch. There is something to discuss/improve.

What about this supply. It's missing in the new binding. Don't we need
it? Isn't it a real supply?

Best regards,

I think it is a leftover from the QMP split. This is a real supply,
but it is used only by UFS PHYs. So, while we are clearing old
bindings, let's drop this unused thing.
