[POWERPC] MSI abstraction
Instead of trying to make PPC64 MSI fit in a Intel-centric MSI layer, a simple short-term solution is to hook the pci_{en/dis}able_msi() calls and make a machdep call. The rest of the MSI functions are superfluous for what is needed at this time. Many of which can have machdep calls added as needed. Ben and Michael Ellerman are looking into rewrite the MSI layer to be more generic. However, in the meantime this works as a interim solution.
