xen: Add some Xen headers
In order to support grub2 in Xen PVH environment some additional Xen headers are needed as grub2 will be started in PVH mode requiring to use several HVM hypercalls and structures. Add the needed headers from Xen 4.10 being the first Xen version with full (not only experimental) PVH guest support.
