Not as far as I know, beyond the limitations on the Affinity
fields (Aff0 recommended to be 0..15, and the total number
allowed via all 4 affinity fields). In any case, if you want
to impose a compile-time limit in the QEMU code then you need
to point out the part of the GIC spec that imposes that limit.
