dt-bindings: Cleanup standard unit properties
Properties with standard unit suffixes already have a type and don't need type definitions. They also default to a single entry, so 'maxItems: 1' can be dropped. adi,ad5758 is an oddball which defined an enum of arrays. While a valid schema, it is simpler as a whole to only define scalar constraints.
