xen: add missing definitions for xen grant table which ia64/xen needs

Add xen handles realted definitions for grant table which ia64/xen
needs.
Pointer argumsnts for ia64/xen hypercall are passed in pseudo physical

guest kernel virtual address into pseudo physical address right before
issuing hypercall.
The xen guest handle represents such arguments.
Define necessary handles and helper functions.
