* @brief Function to setup the DM8168DUCATIPWR module.
*
* This function sets up the DM8168DUCATIPWR module. This function must
* be called before any other instance-level APIs can be invoked.
* Module-level configuration needs to be provided to this
* function. If the user wishes to change some specific config
* parameters, then DM8168DUCATIPWR_getConfig can be called to get the
* configuration filled with the default values. After this, only
* the required configuration values can be changed. If the user
* does not wish to make any change in the default parameters, the
* application can simply call DM8168DUCATIPWR_setup with NULL
* parameters. The default parameters would get automatically used.
*
* @param cfg Optional DM8168DUCATIPWR module configuration. If provided as
* NULL, default configuration is used.

* @sa DM8168DUCATIPWR_destroy
