viafb: remove dead code due to IGA1_IGA2
Some code depended on IGA1_IGA2 which was never set (at least with the
symbolic name). Remove this dead code although it might one day be useful
to get a hint on how some things might work. However as this is dead it
is likely full of bugs and would prevent a clean structure (as it has some
very strange things).
Dead code -> no regressions, at least if VIA doesn't do anything very ugly.
