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.
