[PATCH 08/10] powerpc/mpic_pasemi_msi: Move MSI-related ops to pci_controller_ops

[Daniel Axtens]

Move the PaSemi MPIC msi subsystem to use the pci_controller_ops
structure rather than ppc_md for MSI related PCI controller
operations.

As with fsl_msi, operations are plugged in at the subsys level, after
controller creation. Again, we iterate over all controllers and
populate them with the MSI ops.
