/**
 * Redirect pigweed log prints to chip logging.
 * Currently does not use a log module, but this could be added when needed.
 * pigweed debug and info level logs are mapped to chip's kLogCategory_Detail.
 * All other log levels are mapped to chip's kLogCategory_Error.
 *
 * Note: This function should not be called directly, instead call the functions
 *       in pw_log/log.h.
 *
 * @param[in] level    Pigweed log level.
 * @param[in] flags    Pigweed logging flags, currently these are ignored.
 * @param[in] message  The printf style log string.
