[PATCH] atyfb: VT/GT cleanup
Clean up VT and GT chip descriptions.
All B revision VT chips are called 264VT3. Verified from pictures of the
chips as the specs are a bit unlear in this.
GT revision B1 is Rage II, B2 is Rage II+. Specs and chip pictures seem
to agree.
VT revision A4 is 264VT2. Revision A3 is probably a plain 264VT.
