usb: Add DWC3 model

Browse source 
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.
