dt-bindings: usb: samsung,exynos-dwc3: allow unit address in DTS
The Samsung Exynos SoC USB 3.0 DWC3 Controller is a simple wrapper of
actual DWC3 Controller device node. It handles necessary Samsung
Exynos-specific resources (regulators, clocks), but does not have its
own MMIO address space.
However neither simple-bus bindings nor dtc W=1 accept device nodes in
soc@ node which do not have unit address.
