[PATCH i-g-t 3/6] scripts/xls_to_doc.py: cleanup argparse logic

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

- add a new parameter to optionally generate JSON debug files;
- don't use default formatter;
- don't use args SUPRESS;
- don't use an empty epilog.
