External sensor UART: Switch to DMA TX transfers: The previous version used polling tx function to transfer data. Because of the short command length of the protocols supported this was no big issue. New protocolls (like GNSS) have longer command sequence which have an impact to the program flow. That's why the implementation has been changed to DMA transmission.
