From: Arnd Bergmann <arnd@arndb.de>
Selecting IOMMUFD_DRIVER is not allowed if IOMMUs themselves are not supported:
WARNING: unmet direct dependencies detected for IOMMUFD_DRIVER Depends on [n]: IOMMU_SUPPORT [=n] Selected by [m]: - MLX5_VFIO_PCI [=m] && VFIO [=y] && PCI [=y] && MMU [=y] && MLX5_CORE [=y]
There is no actual build failure, only the warning.
Make the 'select' conditional using the same logic that we have for INTEL_IOMMU and AMD_IOMMU.
