Subject: [PATCH v14 3/5] arm64: dts: qcom: ipq9574: Add USB related nodes

Add USB phy and controller related nodes

SS PHY need two supplies and HS PHY needs three supplies. 0.925V
and 3.3V are from fixed regulators and 1.8V is generated from
PMIC's LDO

 Changes in v13:
	- Move fixed regulator definitions from SoC dtsi to board dts
	- Remove 'dr_mode' from SoC dtsi
	- Move 'status' property to the end
 Changes in v12:
	- Rebase
 Changes in v11:
	- Rename dwc_0 -> usb_0_dwc3
 Changes in v10:
	- Fix regulator definitions
 Changes in v8:
	- Change clocks order to match the bindings
 Changes in v7:
	- Change com_aux -> cfg_ahb
 Changes in v6:
	- Introduce fixed regulators for the phy
	- Resolved all 'make dtbs_check' messages

 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@...00: '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@...0000: '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)
