PCI: rcar: Convert to MSI domains

Browse source

In anticipation of the removal of the msi_controller structure, convert
the Rcar host controller driver to MSI domains.

We end-up with the usual two domain structure, the top one being a
generic PCI/MSI domain, the bottom one being Rcar-specific and handling
the actual HW interrupt allocation.
