[RFC/PATCH 2/4] Allow for non-Intel MSI implementations

[Michael Ellerman]

From: Jake Moilanen <moilanen at austin.ibm.com>

This allows an architecture to provide its own MSI implementation
instead of msi.c and msi-apic.c.  We will need this on IBM System-p
machines where the hypervisor controls the assignment and setup of
MSIs.  A following patch will provide an MSI implementation for these
machines.
