At present there is no way to disable a log driver. But the syslog driver causes (attempted) network traffic in sandbox every time a log message is printed, which is often. Add a flag to enable a log driver. Adjust struct log_device to use a short for next_filter_num so that no more memory is used for devices. Also fix a missing line in the struct log_driver comment while here. To maintain compatibility, enable it for all drivers for now. Signed-off-by: Simon Glass <sjg@chromium.org>
