As we now have forcewake domains, take advantage of it
by putting the differences in gen fw handling in data rather
than in code.

In past we have opencoded this quite extensively as the fw handling
is in the fast path. There has also been a lot of cargo-culted
copy'n'pasting from older gens to newer ones.

Now when the releasing of the forcewake is done by deferred timer,
it gives chance to consolidate more. Due to the frequency of actual hw
access being significantly less.

Take advantage of this and generalize the fw handling code
as much as possible. But we still aim to keep the forcewake sequence
particularities for each gen intact. So the access pattern
to fw engines should remain the same.

not used. We do enable that interrupt currently though, so leaving the
timeout as 0 results in very poor performance as the GPU frequency keeps
dropping constantly. So just program the register with the recommended

Leaving the interrupt enabled doesn't seem to do any harm so far. So

had already landed, which made this the responsibility of the DRM core.
The result was that we were kfree()'ing the state twice, and also
possibly double-unref'ing a framebuffer, leading to memory corruption
when the driver was unloaded.

The fix is to simply not try to cleanup the state in the i915 teardown
code now that the core handles this for us.
