V4L/DVB (5914): Add initial support for Dual-DVB-T stick

Add initial support for Dual-DVB-T stick based on DiB7700 and MT2266

- Microtune MT2266 driver.
- Preliminary support for these dual tuner devices :
  - Pinnacle Dual DVB-T diversity
  - Terratec Cinergy DT USB XS diversity
  - Hauppauge Nova TD USB
