microVU: Setting VU clamp mode to "normal" should fix sps/problems in alot of games now.

I'll list what I think should be fixed:
Dawn of Mana SPS <- Should be fixed, untested
ToTa Characters <- Should be fixed, untested
FFXII SPS in Barheim Passage <- Should be fixed, untested
KH1 floor bug <- Fixed for me, but theres still other sps on characters caused by something else

Most-likely SPS in some other games is fixed as well...
If anyone can confirm the games I listed are fixed, please leave a comment :D
