The guc_info debugfs file is meant to be a quick view of the current software state of the GuC interface. Including the full CTB contents makes the file as a whole much less human readable and is not partiular useful in the general case. So don't pollute the info dump with the full buffers. Instead, move those into a separate debugfs entry that can be read when that information is actually required. Also, improve the human readability by adding a few extra blank lines to delimt the sections. v2: Hide the internal capture/print params from external callers that don't need to know (review feedback from Matthew Brost).
