Some people expressed interest in having possibility to set CRTC <->
outputs mapping at boot time, without having to use 'matroxset' later after
kernel boots.

This patch adds option 'video=matroxfb:outputs:XYZ', where X sets which
CRTC will connect to primary output, Y sets secondary output and Z sets DVI
output.

In addition to that I also added missing memset() into maven, which was
broken since i2c was kobjectified.
