dt-bindings: More whitespace clean-ups in schema files

Clean-up incorrect indentation, extra spaces, and missing EOF newline in
schema files. Most of the clean-ups are for list indentation which
should always be 2 spaces more than the preceding keyword.

Found with yamllint (now integrated into the checks).
