This patch sets the base to use xhci as sysbus model, for which pci
specific hooks are moved to hcd-xhci-pci.c. As a part of this requirment
msi/msix interrupts handling is moved under XHCIPCIState. Made required
changes for qemu-xhci-nec.

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.
