irq_cfg provides a delivery mode for each interrupt. Use it instead
of the hardcoded APIC_DELIVERY_MODE_FIXED. This allows to compose
messages for NMI delivery mode which is required to implement a HPET-
based NMI watchdog.
No functional change as the default delivery mode is set to
APIC_DELIVERY_MODE_FIXED.
