Subject: Use a fast interrupt handler for the PCI version of the cy driver if
 option CY_PCI_FASTINTR is configured and mapping the irq to a fastintr is
 possible.  Unfortunately, this has to be optional because pci_map_int_right()
 doesn't handle the INTR_EXCL flag right -- INTR_EXCL is honoured even if the
 interrupt needs to be non-exclusive for other devices to work.
