powerpc/powernv/pci: Rework pnv_opal_pci_msi_eoi()
pnv_opal_pci_msi_eoi() is called from KVM to EOI passthrough interrupts
when in real mode. Adding MSI domain broke the hack using the
'ioda.irq_chip' field to deduce the owning PHB. Fix that by using the
IRQ chip data in the MSI domain.
The 'ioda.irq_chip' field is now unused and could be removed from the
pnv_phb struct.
