bt8xxgpio.txt: standardize document format
Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx: - Adjust titles to match the convention; - use a literal block for ascii artwork.
