powerpc: Make radeon 32-bit MSI quirk work on powernv
This moves the quirk itself to pci_64.c as to get built on all ppc64 platforms (the only ones with a pci_dn), factors the two implementations of get_pdn() into a single pci_get_dn() and use the quirk to do 32-bit MSIs on IODA based powernv platforms.
