[IA64] make xenLinux/ia64 privcmd mmap not to use dom0 memory

xenLinux/ia64 privcmd mmap uses pseudo physical address space.
it used alloc_pages() to allocate the space.
It wastes dom0 memory and sometimes several hundreds megabytes is
allocated depending on domU memory size.
With this patch xenLinux/ia64 trys to find the region which can be
used safely and uses the reasion.
