power: Add power hint to set profile
* A PowerHAL can implement support for this hint to receive
power profile changes from the framework.

power: Add support for SET_PROFILE hints
* Add support for system performance profiles.
* Uses mpctl to configure the CPUs in the appropriate modes.
* PERFORMANCE = all cores at max
* POWER_SAVE = max two cores at non-turbo voltage
* If a custom profile is set, don't honor any other hints
* Clean up the code and firm up the locking.

power: Update for PerformanceManager changes
* Undo damage caused by the previous patch which broke
all hint arguments. We were actually using these wrong to
begin with anyway.
* Add support for get_profile
* Clean up code

power: Pass NULL parameter in powerHint if data is zero
* This restores the behavior in AOSP and CAF power HAL to avoid
confusion.
