It is useful to name each method so that we can print out this name when using the method. Currently this happens using a separate function. In preparation for unifying this, add a name to each method. The name is only available if we have libcommon support (i.e can use printf()). Signed-off-by: Simon Glass <sjg@chromium.org>
