power: Add specific powerhal for msm8937
* msm8937 is on the same CAF line along with msm8953 and msm8996 and also
supports the MPCTL_V3 commands, in contrast to msm8952. Separate it from
msm8952.

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

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.

* Remove debug logs and useless comments
* Consistent return values
* Add back display hints for legacy platforms, they used to live in
power-common.c but removed in commit 561cffcbfa66192e839e040d2da3bff2ecf8dcac
* Check if set_interactive_override handled hints and print
info message if it didn't
