xen: sysfs: fix build warning.

Define PRI macros for xen_ulong_t and xen_pfn_t and use to fix:
drivers/xen/sys-hypervisor.c:288:4: warning: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'xen_ulong_t' [-Wformat]

Ideally this would use PRIx64 on ARM but these (or equivalent) don't
seem to be available in the kernel.
