Add dt-bindings for USB3 PHY found on Qualcomm IPQ9574
Signed-off-by: Varadarajan Narayanan <quic_varada@xxxxxxxxxxx>
---
Changes in v8:
- Update clock names for ipq9574
Changes in v6:
- Made power-domains optional
Note: In the earlier patch sets, had used the (legacy)
specification available in qcom,msm8996-qmp-usb3-phy.yaml. Moved
to newer specification in qcom,sc8280xp-qmp-usb3-uni-phy.yaml
