The suspend optimizations handling in the driver is being removed. The framework will hence forth control when these optimizations occur - we do this at screen off and hold a short wakelock to ensure this. We also remove the use of the now defunct setsuspendopt command and handle the high perf locking with the new suspend mode command. Change-Id: Ia12e38befb2c4f85cad6612bc8f807805bd0dae1
