Feels like we could just use 'iommu=on' as the name. Also, I'm unclear whether we actually need the 'ats' attribute.
From the description it sounds like if we have device_iotlb=on for the IOMMU device, then we should have ats=on too. Is there a reason to use ats=off when device_iotlb=on, or vica-verca. If not, then we should just do the right thing and set ats=on whenever we see device_iotlb=on.
