Neither simple-bus bindings nor dtc W=1 accept device nodes in soc@ node
which do not have unit address.  Therefore usethe address space
of child device (actual DWC3 Controller) as the wrapper's address to
fix:

  exynos7-espresso.dtb: soc at 0: usb: {'compatible': ['samsung,exynos7-dwusb3'], ...
    should not be valid under {'type': 'object'}
