[PATCH-for-5.2 1/5] hw/usb/hcd-xhci: Make xhci base model abstract

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

The TYPE_XHCI model is abstract and can not be used as it.
It is meant to be overloaded by children classes. Restore
it as abstract type.

Fixes: 8ddab8dd3d8 ("usb/hcd-xhci: Split pci wrapper for xhci base model")
