The forcewake setup is eerily similar, except it needs special mode
flags. Inserting that info into our structure is trivial, and with that
forcewake easily converts to using the new interface as well.
Notice that CRC is lacking from this patch (CRC being very similar to
forcewake in code). CRC is targeted for a new file, so there is no
reason to move it.
