[Savage40] 3D Support for SuperSave IX/C SDR

[Alex Deucher]

One more quick note.  I discovered a bug in the setup of the tiled
surface registers on crtc2 on supersavages.  I'll be committing a fix
tonight.  for those that are interested the offest written to the tiled
surface registers has to be shifted 6 bits rather than 5 in
SavageSetGBD_PM().
