MSI: Combine pci_(save|restore)_msi/msix_state
The PCI save/restore code doesn't need to care about MSI vs MSI-X, all it really wants is to say "save/restore all MSI(-X) info for this device". This is borne out in the code, we call the MSI and MSI-X save routines side by side, and similarly with the restore routines. So combine the MSI/MSI-X routines into pci_save_msi_state() and pci_restore_msi_state(). It is up to those routines to decide what state needs to be saved.
