ISO7816_Init: Initialized with USART 

* ISO7816_Init: Takes Usart_info and CLK_SLAVE/CLK_MASTER as param
* ISO7816_SendChar, ISO7816_GetChar: Usart_info is passed
* ISO7816_Set_Reset_Pin function for CCID part
* iso7816_4.c: BOARD_ISO7816_BASE_USART replaced by USART_SIM
* Redundant _ISO7816_Init, _ISO7816_SendChar, _ISO7816_GetChar
    functions removed
* All simtrace modes use iso7816_4.c functions instead of redefined
    _ISO7816_xxx functions
