Andrew Boie 88808f1247 quark_se: apic: work around EOI forwarding issue 
Quark SE Lakemont core has a hardware bug where the LOAPIC does
not properly notify the IOAPIC to clear the IRR bit for level-
triggered interrupts.

This patch introduces a workaround where the vector ID of the
in-service interrupt is manually written to the IOAPIC_EOI
register, resulting in the bit being cleared.

Unfortunately, in the context where EOI happens it's very difficult
to identify which IRQ line is being serviced, so this is done
unconditionally for all interrupts vectors whether they are registered
in the IOAPIC RTE table or not.
