Remove support for toro

CM has dropped most tuna devices in commit #72826.  Toro has a VERY low
userbase.  (Last build I posted for them 10 days ago got 22 downloads.)
Not worth the time trying to maintain that ourselves. 

If there's anything I missed, just let me know.

PS3: One more file I missed from first PS
