autoport: Drop ioapic, ioapic_irq, and lapic handling for devicetree

The ioapic and ioapic_irq keywords are no longer valid tokens as of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).
Thus, drop them from autoport. Also, the IOAPICIRQs map that this code
relied on to generate ioapic_irq entries never seems to have been
populated by any code in any previous commit, so this appears to have
been dead code since autoport was created.

The lapic keyword was removed from sconfig in commit 15d5183e4af7
(util/sconfig: Remove lapic devices from devicetree parsers) so remove
autoport handling for it as well.
