[PULL 13/20] usb: Add DWC3 model

From:	Peter Maydell
Subject:	[PULL 13/20] usb: Add DWC3 model
Date:	Tue, 15 Dec 2020 14:12:30 +0000
From: Vikram Garhwal <fnu.vikram@xilinx.com>

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.
