[PATCH] hw/usb: Convert to qdev_realize()

[Markus Armbruster <armbru@redhat.com>]

Device code shouldn't mess with QOM property "realized" since we have
proper interfaces (merge commit 6675a653).  Commit 8ddab8dd3d
"usb/hcd-xhci: Split pci wrapper for xhci base model" and commit
f00ff136ee "usb: hcd-xhci-sysbus: Attach xhci to sysbus device"
reintroduced two instances.  Clean them up.  Note that s->xhci is
a (bus-less) TYPE_XHCI device.
