log: use console puts to output trace before LOG init
Use the console puts functions to output the traces before
the log initialization (when CONFIG_LOG is not activated).
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.
