ARM: dts: qcom: ipq8064: drop unused reset-names from DWC3 node

The Qualcomm DWC3 USB controller bindings do not allow "reset-names" and
Linux driver does no use it.  This fixes dtbs_check warning:

  qcom-ipq8064-ap148.dtb: usb@100f8800: 'reset-names' does not match any of the regexes: '^usb@[0-9a-f]+$', 'pinctrl-[0-9]+'
