Revert "smdk4412: add more governor"

While various logs indicate that adaptive is currently the primary cause of hungtask timeout reboots, I wouldn't be surprised if these governors are crap too.

Alternate governors rarely provide anything that can't be achieved with small tuning of the existing mainline governors.  There's a reason mainline doesn't have all of this additional crap...

Rip them out until their merits can be proven, one governor at a time.

This reverts commit c2d3d194813a1db30e2cb8bd475a20a5c6ba6996.
