[PATCH] v4l: SAA7134 hybrid DVB

- Add new Typhoon DVB-T Cardbus.
- DVB-T support for MD7134 cardbus and the PCI variants
- initial DVB-T support for Lifeview Flydvb-t duo
- DVB-T support for Philips TOUGH reference design
- Don't turn off the xtal output of tda8274/75 in sleep mode
- Let Kconfig decide whether to include frontend-specific code in saa7134-dvb.
- Removed unused structures.
