In practice, it is the maximum number of distinct interrupt sources to expect on Intel systems, used to size the IR table appropriately (on AMD, they are device-bound, so you shouldn't have a need for this). As we have no SMMU for ARM yet, I'm not sure if there will be a reuse. If not, we can make it x86-only.
