It does not make much sense to have KVM in book3s-64bit and
not to have IOMMU bits for PCI pass through support as it costs little
and allows VFIO to function on book3s-kvm.

Having IOMMU_API enabled will make it unnecessary to have a lot of
IOMMU_API enabled, those files only accelerate user space emulated devices
which do not seem to be in use very often.
