Jason Gunthorpe 01f70cbb26 iommufd: Allow iommufd to supply /dev/vfio/vfio 
If the VFIO container is compiled out, give a kconfig option for iommufd
to provide the miscdev node with the same name and permissions as vfio
uses.

The compatibility node supports the same ioctls as VFIO and automatically
enables the VFIO compatible pinned page accounting mode.
