Revert "smdk4412: activate dormant governors"

Adaptive is causing all sorts of issues, including spontaneous reboots (esp. in recovery) due to hung task timeouts on basically any device that doesn't have it set to default.

We'll want conservative across the board, we'll reenable that once we fix hotplugging on 4412 devices...

This reverts commit dcecf56b6e77948cf2db8a661c57d5480fa2a268.

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.
