tms57002: Add two missing instructions and hack up the coef update.

Browse Source 
The real way coefficient updates are handled is a little too complex
for now, but the hack throttles the update speed to the real rate
given the way konami uses it (once per sync).  It's near impossible to
use it in a different way anyway.

Fixes mantis 2941 (at least for puzldama) and maybe 2953 (needs to
find the roms and test).
