V4L/DVB (11364): tuner: remove i2c legacy code. 

All drivers that use the tuner module now use v4l2_subdev, so we can remove the
legacy code from this module.

Note that TUNER_SET_CONFIG is still called by tuner-simple.c, so we have
to handle it via a .command callback. There must be a better way to do this,
but for now this will work.
