parisc: Do not reprogram affinitiy on ASP chip

commit dca7da244349eef4d78527cafc0bf80816b261f5 upstream.

The ASP chip is a very old variant of the GSP chip and is used e.g. in
HP 730 workstations. When trying to reprogram the affinity it will crash
with a HPMC as the relevant registers don't seem to be at the usual
location.  Let's avoid the crash by checking the sversion. Also note,
that reprogramming isn't necessary either, as the HP730 is a just a
single-CPU machine.
