This patch adds skeleton model of dwc3 usb controller attached to xhci-sysbus device. It defines global register space of DWC3 controller, global registers control the AXI/AHB interfaces properties, external FIFO support and event count support. All of which are unimplemented at present,we are only supporting core reset and read of ID register.
