s390/pci: reduce iomap size (even more)

Commit c506fff ("s390/pci: resize iomap") reduced the iomap to NR_FUNCTIONS * PCI_BAR_COUNT elements. Since we only support functions with 64bit BARs we can cut that number in half. Signed-off-by: Sebastian Ott <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
