ARM: dts: qcom: ipq4019: use generic node names for USB

Device node names should be generic which is also expected by USB
bindings:

  qcom-ipq4018-jalapeno.dtb: dwc3@6000000: $nodename:0: 'dwc3@6000000' does not match '^usb(@.*)?'

Override also the DWC3 node in qcom-ipq4018-ap120c-ac.dtsi by
label/phandle, not via node path, because it is less error-prone and
makes the overriding node-name independent.
