* Function:         core_get_advertised_current
* Input:            None
* Return:           Advertised current in mA
* Description:      Returns advertised source current. 
*                   A '0' is returned if advertised current is 0mA, device is a 
*                   Source, or there is no Type-C contract.
*                   Note: Default is set to return the minimum value, 500mA
*                   This can be:  
*                       500mA for USB 2.0
*                       900mA for USB 3.1
*                       Up to 1.5A for USB BC 1.2
*                   It is up to the device to determine the USB Type
