xen: Introduce xen_pfn_t for pfn and mfn types
All the original Xen headers have xen_pfn_t as mfn and pfn type, however when they have been imported in Linux, xen_pfn_t has been replaced with unsigned long. That might work for x86 and ia64 but it does not for arm. Bring back xen_pfn_t and let each architecture define xen_pfn_t as they see fit.
