select can be used on tristates perfectly fine.

So the dependencies are:
- VFIO - duh, yeah, anything vfio related needs to select that.
But this is a perfectly fine transitive select
- PCI - yeah. But we can expect everything that selects VFIO_PCI_CORE
to select PCI. Or a transitive select would be fine again
- EVENTFD this is another classic transitive one that should just be selected
instead of a user asking why it is not set
- MMU: I suspect all of VFIO and thus the menuconfig really should
depend on that
So not really an issue here. VFIO_PCI_CORE really is underlying
infrastructure a user should not care about.
