I still don't understand what the point of enabling ACPI for arm64
during this series is. Do you get any working arm64 functionality
(on hardware or model) without subsequent patches? If it's just for
compilation reasons, the best we could do is depending on (ARM64 &&
COMPILE_TEST) but even though I would not merge this patch until we have
most of the arm64 required features in place (some of which are
introduced by the upcoming ACPI version).

For the benefit of single Image, I think you can default to y here.
