Ustellar UT99911 RGB: rename attributes without spaces

- don't bother to map values for app_mode, as the original values are enough to identify the meaning, and the attribute is not important enough to add the extra complexity.

- revert dp 103 type to string, it seems the review comment was misinterpreted.
