Revert "Add device enumeration interface (v4)"

This reverts commit fde4969176822fe54197b6baa78f8b0ef900baba.

The commit adds an API that does not seem flexible enough to be used in
current open-source projects. Additionally it adds a hidden dependency
of libudev, which when used in mesa caused grief when combined with
Steam('s runtime).

Let's revert this for now and add a tweaked API later on that can be
used in mesa/xserver.
