puc(4): Tighten expression of supported modules

Since we have a huge number of supported device here, try to consolodate
entries that make sense and do other formatting tweaks to reduce the raw
number of lines needed to express the supported models. Also, the
oxford semi blur the line between chip support and board support, so
simplify that entry. Simplify the SIIG stuff somewhat (while the
pucdata has per-chip entries, we don't need that here since we support
virtually all SIIG cards). Place several entries on the same line where
(I think) it makes sense.

This could likely stand to be put into alphabetical order.
