xhci: fix nec-usb-xhci properties
Storing properties directly in XHCIPciState.xhci doesn't work, the object_initialize_child() call in xhci_instance_init() will overwrite them. This changes the defaults for some properties, which in turn breaks live migration and possibly other things as well. So add XHCINecState, store properties there, copy them over on instance init.
