When CONFIG_LOG is activated, if LOG_DEBUG is defined in a file and DEBUG is not defined the trace with debug() macro are not displayed, because the parameter cond : _DEBUG = 0 is checked in debug_cond().
With this patch the define DEBUG, used to force the trace generated by debug() macro, is linked with the define LOG_DEBUG, used to force the trace generated by other macros (log_debug, dev_dbg, pr_debug).
We only need to define LOG_DEBUG in a file to activate all the traces generated by any U-Boot debug macro, as it is described in /doc/develop/logging.rst
