V4L/DVB (11864): cx18: Complete support for Sliced and Raw VBI for 625 line systems
Finish changes for sliced and raw VBI for 625 line systems. Tested with VPS
and WSS being emitted by a PVR-350 in field 1 lines 16 and 23.

* For 625/50 systems, according to the VIP 2 & BT.656 std:
* The EAV RP code's Field bit toggles on line 1, a few lines
* after the Vertcal Blank bit has already toggled.
- * Tell the encoder to capture 23-1+1=23 lines per field,
- * since we want lines 6 through 23.
