Always turn on the TAM_DEBUG3=0x6 workaround on real r200s. It appears that

the current cases for turning it on were insufficient (Bugzilla #1519, 729, 814)
and it has no significant performance impact.  Performance tested with quake3
in GL_LINEAR mode both with and without anisotropy, with the workaround always
on or always off.
