PCI: Add managed pcim_intx()
pci_intx() is a "hybrid" function, i.e., it is managed if
pcim_enable_device() has been called, but unmanaged otherwise.
Add pcim_intx(), which is always managed, and implement pci_intx() using
it.
Remove the now-unused struct pci_devres.orig_intx and .restore_intx and
find_pci_dr().
