  Add USB phy and controller related nodes

Signed-off-by: Varadarajan Narayanan <quic_varada@quicinc.com>

 Changes in v5:
	- Fix additional comments
	- Edit nodes to match with qcom,sc8280xp-qmp-usb3-uni-phy.yaml
	- 'make dtbs_check' giving the following messages since
	  ipq9574 doesn't have power domains. Hope this is ok

		/local/mnt/workspace/varada/varda-linux/arch/arm64/boot/dts/qcom/ipq9574-al02-c7.dtb: phy@7d000: 'power-domains' is a required property
        	From schema: /local/mnt/workspace/varada/varda-linux/Documentation/devicetree/bindings/phy/qcom,sc8280xp-qmp-usb3-uni-phy.yaml
		/local/mnt/workspace/varada/varda-linux/arch/arm64/boot/dts/qcom/ipq9574-al02-c7.dtb: usb@8a00000: 'power-domains' is a required property
        	From schema: /local/mnt/workspace/varada/varda-linux/Documentation/devicetree/bindings/usb/qcom,dwc3.yaml


 Changes in v4:
	- Use newer bindings without subnodes
	- Fix coding style issues

 Changes in v3:
	- Insert the nodes at proper location

 Changes in v2:
	- Fixed issues flagged by Krzysztof
	- Fix issues reported by make dtbs_check
	- Remove NOC related clocks (to be added with proper
	  interconnect support)

No, I think it is not.

There are no GDSCs in IPQ9574. Can you suggest how to proceed.

You need to update the binding and either make the power domains
property optional in the binding or dependent on the SoC.

Thanks for the heads up. But for future submission, please try to
