DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. While touching the lines do other non-functional changes: replace raw number with proper define for GPIO flag and use generic node name. No functional changes here, but saves some comments during reviews of new patches built on existing code.
