/**
Initialize the power management support.
This function will do boot time configuration:
Install into SMRAM/SMM
Detect HW capabilities and SW configuration
Initialize HW and software state (primarily MSR and ACPI tables)
Install SMI handlers for runtime interfacess
@param[in] ImageHandle Pointer to the loaded image protocol for this driver
@param[in] SystemTable Pointer to the EFI System Table
@retval EFI_SUCCESS The driver installed/initialized correctly.
@retval Driver will ASSERT in debug builds on error. PPM functionality is considered critical for mobile systems.
