In fact, my comment is partially wrong I noticed... That is, some of
those seem to have a 8259. In this case, the 8259 interrupts are always
down at 1...15 and can perfectly be hard coded in fixups as there is
always a 1:1 mapping between virq and hwirq for 8259 (that's what the
HOST_LEGACY choice is, specifically for 8259).
