[3/5,v2] dt-bindings: gnss: Rewrite sirfstar binding in YAML

This rewrites the SiRFstar DT bindings in YAML.

ChangeLog v1->v2:
- Change additionalProperties: false to uneavaluatedProperties: false
  so new common properties get available immediately
- This should also make the checker robot happy about
  lna-supply

I fixed up both and applied.
