* Name: up_pminitialize
*
* Description:
* This function is called by MCU-specific logic at power-on reset in
* order to provide one-time initialization the power management subystem.
* This function must be called *very* early in the initializeation 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.
