For kexec on xen xen_machine_kexec_register_resources() needs
to be called at boot time.

Guard by is_initial_xendomain() so as not to break transparent
virtualisation, as suggetsed by Alex Williamson. is_initial_xendomain()
is used instead of is_running_on_xen() as this isn't supposed
to do anything on non-privelaged domains (yet). Also conform that
this code is pretected by CONFIG_KEXEC.
