powerpc/pseries/pci: Introduce rtas_prepare_msi_irqs()

Browse source

This splits the routine setting the MSIs in two parts: allocation of
MSIs for the PCI device at the FW level (RTAS) and the actual mapping
and activation of the IRQs.

rtas_prepare_msi_irqs() will serve as a handler for the PCI MSI domain.
