And if it IS required when using libvirt with pci passthrough, but not
necessarily for other users of libpciaccess, then we can make libvirt
select it.

In the general case for nice-to-have-but-not-absolutely-required
dependencies we don't have a solution in Buildroot today except for a
note in the help text. Upstream kconfig has recently added the imply
keyword which could be used to implement this, but we would need to sync
our kconfig with upstream for that.
