|  Purpose :  This Module defines the power management device driver
|             for the G23 protocol stack.
|             
|             This driver is used to control all power related functions 
|             such as charger and battery control. The driver does support
|             multiple devices and therefore no open and close functionality
|             is supported. The driver can be configured to signal different
|             state transitions, for example battery level has reached the
|             "battery low" level. This is done by setting an OS signal or 
|             calling a specified call-back function.

  PURPOSE : The function initializes the driverīs internal data.

            failure, which means the that the driver cannot be used,
            the function returns DRV_INITFAILURE.

            removed. If the SignalID provided can not be found, the
