 * Name: arm_pminitialize
 *
 * Description:
 *   This function is called by MCU-specific logic at power-on reset in
 *   order to provide one-time initialization the power management subsystem.
 *   This function must be called *very* early in the initialization sequence
 *   *before* any other device drivers are initialized (since they may
 *   attempt to register with the power management subsystem).
 *
 * Input Parameters:
 *   None.
 *
 * Returned Value:
 *   None.
