Hartmut Hackmann 9971f4f1d3 V4L/DVB (5485): Tda827x: delayed probing of tuner version 
When the tuner is attached, the tda10046 is not initilized yet, so it
is searching for its firmware. If the tuner is attached to the tda10046
silent i2c port, a bus collision can occur. Now the version is probed
during the first init or sleep call.
