schema.yaml: Fix ftdi_gpio patternProperties

"patternProperties" must be on the same indentation level as "properties",
otherwise it just defines a property called "patternProperties" in
cdba.yaml.

Also add additionalProperties: false, so properties not matching the regex
are actually disallowed and reported.
