ostc4: Small_CPU/Src/uart.c annotate

annotate Small_CPU/Src/uart.c @ 922:7c996354b8ac Evo_2_23

Moved UART6 into a separate unit: UART6 connects internal devices. As a first step the existing code sections have been moved into a new unit. As well the code of the external GNSS sensor has been copied into this unit as starting point for the further development. Later the internal part can be integrated into the common uart (code cleanup).
