Instead of one global log level option and one on/off boolean config option / module, this commit creates one log level option for each module. This simplifies the logging as it is now possible to enable different level of debugging output for each network module individually. The commit also converts the code to use the new logger instead of the old sys_log. Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com>
