Let drivers specify interrupt flags (INTR_EXCL and/or INTR_FAST)

using the new pci_map_int_right() variant of pci_map_int().  Fast
interrupts work for PCI devices if and only if they are exclusive.
(The PCI interrupt mux doesn't support fast interrupts and can't
support a mixture of fast and slow interrupts even in principle.)

Don't assume that intrmask_t == unsigned in pci_map_int().
