[PATCH] fix vpx3220 offset issue in SECAM

Browse source 
Fix bug #5404 in kernel bugzilla.

It basically updates the vpx3220 initialization tables with some newer
values that we've had in CVS for a while (and that, for some reason, never
ended up in the kernel...  must've gotten lost).  Those fix a ~16 pixels
noise at the top of the picture in at least SECAM, although (now that I
think about it) PAL was probably affected, also.
