Use the debug uart functions to output the traces before the log initialization (when CONFIG_LOG is not activated) as it is done in puts/putc function in console.c.
This patch allows to display the first U-Boot traces (with macro debug) when CONFIG_DEBUG_UART is activated and not only drop them. For example for traces in board_f.c requested by the macro debug, when LOG_DEBUG is defined and CONFIG_LOG is activated.
