Since commit 42ac9bd18d4f ("vfio: initialize the virqfd workqueue in
VFIO generic code"), vfio itself depends on EVENTFD support. Add this
to Kconfig to enforce the dependency. This could perhaps become a
soft dependency if there was sufficient interest to make it more
modular, but eventfds are currently an integral part of vfio interrupt
delivery for all vfio bus drivers.
