st/nine: Use TGSI_SEMANTIC_GENERIC for fog
We used TGSI_SEMANTIC_FOG for fog, however on vs/ps 3, fog is allowed to have 4 components (even on the ff pipeline according to a wine test). Since gallium's TGSI_SEMANTIC_FOG has only one component, use TGSI_SEMANTIC_GENERIC instead. Fixes: https://github.com/iXit/Mesa-3D/issues/346 Signed-off-by: Axel Davy <davyaxel0@gmail.com>
