[linux-dvb] [PATCH] experimental support for C-1501

[Sigmund Augdal <sigmund@snap.tv>]

The following experimental patch adds support for the technotrend budget
C-1501 dvb-c card. The parameters used to configure the tda10023 demod
chip are largely determined experimentally, but works quite for me in my
initial tests.
