There are no hardware requirements to use the same delivery mode for all
interrupts. Use the mode specified in the provided IRQ hardware
configuration data. Since all IRQs are configured to use the delivery mode
of the APIC drive, the only functional changes are where IRQs are
configured to use a specific delivery mode.
