PerformanceManager: Allow wait for MPCTL to start on boot

 * For devices using Qualcomm MPCTL interface as power profile backend,
   setting the user's profile preference fails on boot, because we call
   perf_lock_acq before MPCTL is ready.
 * To fix the issue, add an option to wait for MPCTL service to start
   before setting stored power profile.
 * We should not only wait for the service to start but also post boot
   parsed property to be set, because MPCTL service won't actually
   initialize if the property is not set to 1.
