Disable i8042 check on Apple machines

Hi Bastien and Dmitry,

I was going through some of the patches we're carrying in Fedora and
came across this one that Bastien submitted a long time ago:

http://lkml.indiana.edu/hypermail/linux/kernel/1005.0/00938.html

It works and we're still carrying it, but Dmitry said it needed to be
done differently in i8042-x86ia64io.h.  Would that just mean adding a
DMI for Apple machines to the i8042_dmi_nopnp_table struct?  Or
exactly what should be done here?

I'd like to get this upstream.
