Fix MSI-related build problems on ia64.
Move arch/ia64/sn/pci/msi.c to drivers/pci/msi-altix.c
Move struct msi_ops in drivers/pci/msi.h to the top of the file so asm/msi.h
can make use of the declaration.
Clean up msi platform defintions in machvec.h (thanks to [email protected]
for the patch to do that).
