[PATCH][DVB][2.6.12]Siemens DVB-C PCI: SAA7113 Analog Module Extension: Fix missing Video (CVBS+Y/C) Inputs in AV711X V4L driver

[thomas schorpp <t.schorpp@gmx.de>]

hello,

this patch enables the before not implemented video inputs of the
SAA7113 Analog Cable Extension Module of that "classic" dvb-c card
listed:

http://www.vdr-wiki.de/wiki/index.php/DVB-C_full-featured-Karten#Fujitsu-Siemens_DVB-C

- tested O.K. with original Siemens PCI Card + CI + Analog Module
- tested O.K. with xawtv (latest 3.xx release at this time)
- tested O.K. with gnomemeeting (v4l1 only)
- tested O.K. with tvtime 0.9x (NOT OK if tuner is accessed! be careful)
- not tested the Y/C input configuration, is guessed from datasheet.
