Qualcomm SuperSpeed DWC3 USB SoC controller

Required properties:
- compatible:	should contain "qcom,dwc3"
- clocks:		A list of phandle + clock-specifier pairs for the
				clocks listed in clock-names
- clock-names:	Should contain the following:
  "core"		Master/Core clock, have to be >= 125 MHz for SS
				operation and >= 60MHz for HS operation

Optional clocks:
  "iface"		System bus AXI clock.  Not present on all platforms
  "sleep"		Sleep clock, used when USB3 core goes into low
				power mode (U3).

Required child node:
A child node must exist to represent the core DWC3 IP block. The name of
the node is not important. The content of the node is defined in dwc3.txt.

Phy documentation is provided in the following places:
