autoport: Drop ioapic devicetree entry generation

The ioapic and ioapic_irq keywords are no longer valid as of commit
e84b095d3a23 (util/sconfig: Remove unused ioapic and irq keywords), and
the associated driver had previously been removed in commit ca5a793ec31c
(drivers/generic/ioapic: Drop poor implementation), so drop it from
autoport. The IOAPICIRQs map that this code relied on to generate
entries never seems to have been populated anyway in any commit so this
has always essentially been dead code.
