radeonsi: always prefer SWITCH_ON_EOP(0) on CIK
The code is rewritten to take known constraints into account, while always
using 0 by default.
This should improve performance for multi-SE parts in theory.
A debug option is also added for easier debugging. (If there are hangs,
use the option. If the hangs go away, you have found the problem.)
