Subject: lxfb: set the H- and V-SYNC polarity of the flatpanel output
From: Michael Grzeschik <m.grzeschik@xxxxxxxxxxxxxx>
Fixup for the flatpanel output. The geode_modedb attribute flags are used
to set the SYNC polarity of the flatpanel. Without this patch our
flatpanel registers stayed unconfigured, so we just saw garbage output.
