Daniel De Graaf 2c5d37d30f xenbus: Support HVM backends
Add HVM implementations of xenbus_(map,unmap)_ring_v(alloc,free) so
that ring mappings can be done without using GNTMAP_contains_pte which
is not supported on HVM.  This also removes the need to use vmlist_lock
on PV by tracking the allocated xenbus rings.
