arm64: dts: apm: Harmonize DWC USB3 DT nodes name

In accordance with the DWC USB3 bindings the corresponding node
name is suppose to comply with the Generic USB HCD DT schema, which

"^usb(@.*)?" . Make sure the "snps,dwc3"-compatible nodes are correctly
named despite of the warning comment about possible backward
compatibility issues.
