[linux-dvb] reload grundig_29504-401 patch

[Andrew de Quincey <adq_dvb@lidskialf.net>]

Hi, I noticed that (on a Hauppague WinTV Nova-T) if you unload and
reload the grundig_29504-401 module, it fails to detect the frontend
after the first detection.

The following patch removes this limitation.. however to do this, it has
to remove a check for an EEPROM. I unfortunately cannot locate the
datasheet for the LSI Logic L64781 chip (I can only find the L64780
which appears to have a different register set), so I'm unable to design
a better detection solution.... if someone wants to send me this
document, I can see if something better is possible.
