In cases where we don't reference another schema, 'additionalProperties' can be used instead. This is preferred for now as 'unevaluatedProperties' support isn't implemented yet. In a few cases, this means adding some missing property definitions of which most are for SPI bus properties. 'unevaluatedProperties' is not going to work for the SPI bus properties anyways as they are evaluated from the parent node, not the SPI child node.
