V4L/DVB (3395): Fixed Pinnacle 300i DVB-T support

- fixed tda9886 port 2 setting
- turned remote control receiver off via saa7134 GPIO to avoid i2c hangs
- modified tda9886 client calls to direct i2c access to allow proper return
  to analog mode
- allow mode change to V4L2_TUNER_DIGITAL_TV in tuner VIDIOC_S_FREQUENCY
  client call
