[PATCH v3 00/12] microvm: add second ioapic

[Gerd Hoffmann]

Add a second ioapic to microvm.  Gives us more IRQ lines we can
use for virtio-mmio devices.  Bump number of possible virtio-mmio
devices from 8 to 24.

v3:
 - pick up some review tags.
 - replace magic numbers with #defines.
 - add asl changes to commit messages.
v2:
 - reorganize code a bit.
 - add ioapic2= option to microvm.
