Documentation/acpi/gpio.md: Fix markdown heading levels
Only the document title should be a top-level heading ('#'). Everything
else should be a second- over lower-level heading ('##').
Also remove the '#' sign at the end of heading lines. "# Foo #" is
mentioned as a valid syntax variant at [1], but it's quite uncommon.
