rdtech-dps: address simple style issues

Coding style nits: Use const data for model lists. Prefer size types.
Link sdi and devc immediately after allocation. Skip unused wire fields
by reading them too, avoid breaking the reviewer's flow.

Cosmetics, readability: Do place trailing commas in initializers. Reduce
text line length. Break long lines in more appropriate locations that
are more readable. Eliminate unmotivated pre-increment operators.
