I've send the patches to provide .has_semaphores and .has_rc6 features not
that long ago, perhaps it is time to reconsider them to simplify such

The logic behind their rejection at that time was that it not the right
things to rely on such flags for feature functionality status (in that
time, I intended to use them to make rc6/semaphores available on IVB by
default - in yet another attempt to have somewhat working default for each
gpu generation). But perhaps we could use those just to announce which GPUs
has the features instead of relying on IS_GEN checks? This would cover the
RC6, Turbo and Semaphores items for now for example.
