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:
exynos5250-smdk5250.dtb: soc: usb3: {'compatible': ['samsung,exynos5250-dwusb3'],
... } should not be valid under {'type': 'object'}
exynos5250.dtsi:638.16-653.5: Warning (simple_bus_reg): /soc/usb3: missing or empty reg/ranges property
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

Changes since v1:
1. Use ranges with values and drop reg from usb-wrapper node.
2. Keep "usb" as wrapper's node name.
