Added back rs400_mc_wait_for_idle - maybe final patch?

I was actually thinking about keeping that part, but it was a do-or-don't
decision. Added a patch that is basically variant 1, but keeps the mentioned
rs400_mc_wait_for_idle call parts untouched. Also I have obsoleted the earlier
two variants.

Is this final patch for this issue maybe? I do not know if anyone still have
glitches with HyperZ on r300 (I do not have any at all), but this kind of heavy
glitches should at least go away now completely for everyone.
