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 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

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)
