[linux-dvb] Patch for cards with the Philips CD1516 tuner box (spXXXX?)

[Juha Yrjölä <jyrjola@cc.hut.fi>]

I managed to get my Fujitsu-Siemens PCI-DVB Cable card to tune to the
whole frequency range (130..460 MHz) by patching the driver. The diff
against the latest CVS HEAD is attached.

I also cleaned up the tuner_set_tv_freq() function a bit.

Cheers,
Juha
