Currently ARM QEMU generates, and reports, MADT revision 4. ACPI 6.3
introduces MADT revision 5.
For MADT revision 5, the GICC structure adds an SPE Overflow Interrupt
field. This new 2-byte field is created from the existing 3-byte
Reserved field. The spec indicates if the SPE overflow interrupt is
not supported, to zero the field.
