xen: implement updated XENMEM_add_to_physmap_range ABI
Allows for more fine grained error reporting. Only used by PVH and ARM both of which are marked EXPERIMENTAL precisely because the ABI is not yet stable Signed-off-by: Ian Campbell <ian.campbell@citrix.com> [v1: Rebased without PVH patches] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
