usb/hcd-xhci: Split pci wrapper for xhci base model

Browse Source 
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.
