I didn't want to make it automatic because the openpic specification says
you only have to support 8-bit vectors. So if there's an implementation
out there with 256 sources and only 8-bit vectors (and we put IPI/timers
above 256), things will break instead of the uppermost sources just not
being usable/valid.

If noone is worried about that, then I'm fine with doing it automatically
instead.
