Subject: [PATCH 2/3] s390: Use the generic msi.h

Without this I can't enable PCI_MSI_IRQ_DOMAIN, which as far as I can
tell only depends on generic functionality provided by msi.h.
PCI_MSI_IRQ_DOMAIN has historically had a whitelist of supported
architectures, but that list is getting long enough that it's cleaner to
just enable it everywhere.

This builds with an s390 defconfig, but I have no access to s390 and
therefor can't even boot test it.
