xen/acpi: Move the xen_running_on_version_or_later function.

Browse source 
As on ia64 builds we get:
include/xen/interface/version.h: In function 'xen_running_on_version_or_later':
include/xen/interface/version.h:76: error: implicit declaration of function 'HYPERVISOR_xen_version'

We can later on make this function exportable if there are
modules using part of it. For right now the only two users are
built-in.
