[PATCH v11 18/28] hw: arm: virt-acpi-build: add hack

[Mohamed Mediouni <mohamed@unpredictable.fr>]

Looks like in the prior Qemu ACPI table handling, GICv2 configurations
had vms->its=1...

Match that assumption to not make the test suite fail. Probably not merge-worthy...

And then maybe see what to do for older releases too?
