[PATCH] matroxfb: Set maxhipri to 0

The current init code sets hiprilvl to 0 and maxhipri to 5.  According to the
specs those values are illegal on both G200 and G400.  It also causes
distortions on the TV-out at least when CRTC2 is in YUV mode as is the case
with DirectFB.  This patch resets both values to 0.
