Xen: ARM: Zero reserved fields of xatp before making hypervisor call
Ensure all reserved fields of xatp are zero before making hypervisor call to XEN in xen_map_device_mmio(). xenmem_add_to_physmap_one() in XEN fails the mapping request if extra.res reserved field in xatp is not zero for XENMAPSPACE_dev_mmio request.
