x86, ioapic: Teach mp_register_ioapic to compute a global gsi_end
Add the global variable gsi_end and teach mp_register_ioapic
to keep it uptodate as we add more ioapics into the system.
ioapics can only be added early in boot so the code that
runs later can treat gsi_end as a constant.
Remove the have hacks in sfi.c to second guess mp_register_ioapic
by keeping t's own running total of how many gsi's have been seen,
and instead use the gsi_end.
