The define PR was introduced to switch quickly between TRACE levels
for specific debug print messages.
Now, it all became debug output, since it is not needed in normal
operation.
* 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
Based on the sniff with a logic analyzer the time when the RST line
is holded low by simtrace is too short.
A better timeout value should be searched for later anyways.
