ia64/pv_ops/xen: elf note based xen startup.
This patch enables elf note based xen startup for IA-64, which gives the kernel an early hint for running on xen like x86 case. In order to avoid the multi entry point, presumably extending booting protocol(i.e. extending struct ia64_boot_param) would be necessary. It probably means that elilo also needs modification.
