Currently a hack. Need to define a polite way of defining IRQ_BITMAP_BITS

Well... given how IRQ_BITMAP_BITS is used, it looks like simply having a sufficiently high number is all that is needed. The current value appears to be totally arbitrary (and having 8196 instead of 8192 there is rather odd). So I think this shouldn't need to be defined in terms of NR_IRQS at all in fact.
