When running unit tests, some may have side effects which cause a subsequent test to break. This can sometimes be seen when using 'ut dm' or similar. Add a new argument which allows a particular (failing) test to be run immediately after a certain number of tests have run. This allows the test causing the failure to be determined. Update the documentation also. Signed-off-by: Simon Glass <sjg@chromium.org>
