Don't assume we have legacy PICs (i.e. 8259A in cascade) at the legacy
I/O port addresses. Even if we do, this is hardly the place to mask
interrupts. It's not clear that this was at all needed. The code came
with CVS revision 1.2 of nexus.c when interrupt support was first added.
What is known is that ia64 has always been designed around the IOSAPIC,
and that doing I/O like this prevents Altix from booting.
