One other thing - it doesn't seem to be 100% desirable to making the
allocation of the IRQ descriptors depend on not specifying a base - for
many situations we're likely to want to know what the numbers we end up
with are (eg, for passing to another device) but if we don't call
irq_alloc_decs() the platform still has to arrange for the descriptors
to be there in advance.  It feels like the code should always use
irq_alloc_descs(), though obviously that's not going to work right now.
