crystalhd: Switch to new decode API and remove the insanity
The new decode API allows for m:n decode patterns, which is what
you need to use this hardware in a sane way. There are so many
situations where 1:1 doesn't happen naturally that it's a miracle
I got it working as well as I did.
With this change, we can throw all of the crazy heuristics and
sleeps(!) out, and things work correctly.
