Subject: target-helpers: add dd_configuration(), dd_driver_name()

Add a couple of helpers to be used by the dri targets when
built with static pipe-drivers. Both functions provide
functionality required by the dri state-tracker.

With this patch ilo, nouveau and r300 gain support for
throttle dri configuration.
