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

Leave MIN_FREQ as default except for high performance profile.
Besides, big cluster is turned off by power_set_interactive_ext when display off for some 8939 device.
So, MIN_FREQ tweak would not work anyway.

power: Handle launch and interaction hints for perf HAL platforms
* MP-CTL does not handle POWER_HINT_INTERACTION and POWER_HINT_LAUNCH
directly. Requests for processing are sent by Qualcomm BoostFramework
(QPerformance) at the framework service level. Since we do not have
BoostFramework, process POWER_HINT_INTERACTION and POWER_HINT_LAUNCH
in PowerHAL to ensure a sufficient level of performance.
* For proper operation, perfboostsconfig.xml file is required.

power: don't use SCROLL_PREFILING
The current use of the SCROLL_PREFILING hint hurts scroll performance
and results in a lot of dropped frames.
The hint ID corresponding to SCROLL_PREFILING only takes into effect for
a default timeout value of 80 ms (as found in perfboostsconfig.xml),
while the duration value in the process_interaction_hint function runs
for a much longer time, from 1500 ms up to 5000 ms (bounds of
kMinFlingDuration and kMaxInteractiveDuration). During the period
of time, when the timeout value has elapsed and current time is less
than duration, another interaction hint cannot be processed. Therefore,
if the user decides to scroll during this period, high frame drops can be
experienced as the CPU freq isn't raised by processing another hint to
account for this additional scrolling.
By only using SCROLL_VERTICAL, fluidity can be maintained, improving user
experience.
Furthmore, kMinInteractiveDuration has been lowered to 400 ms for some
platforms as it is more than sufficient to maintain fluidity (minimal
frames dropped) while scrolling.

power: Release launch boost perflock when launch is completed
Currently, the launch boost perflock is held for a fixed duration, either
specified in perfboostsconfig.xml for perf HAL platforms or hardcoded in the
powerHAL for non-perf HAL platforms.
Using a fixed duration for this perflock has two shortcomings:
* perflock can be held for too long, causing the CPU freq and other resources
to be boosted for too long even if the application has finished launching,
resulting in excessive battery drainage
* perflock can be held not long enough if it takes more than the timeout
time to finish launch
The framework sends out a powerhint for both when launch starts and when
launch ends. The launch finish hint can be used to signal when to release the
perflock.
