This isn't entirely common to all chips. It's been BIT(3) for most of
history and is for all the chips in the series. But there upcoming chips
where it'll be different. There are only a finite number of ACV bits
available, so depending on the requirements they can be repurposed. We
should probably just have the raw mask defined in the target files.
