[PATCH v2 2/4] hw/acpi: arm: bump MADT to revision 5

[Eric DeVolder <eric.devolder@oracle.com>]

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.
