dt-bindings: Whitespace clean-ups in schema files

Clean-up incorrect indentation, extra spaces, long lines, 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 (which I plan to integrate into the checks).
