V4L/DVB (6127): tuner: kill i2c_client interface to tuner sub-drivers
To ease the conversion of the analog tuner sub-drivers into dvb_frontend style tuner modules, we must remove the i2c_client interface. dvb_frontend style tuner modules use i2c_transfer directly on the i2c_adapter. This change only alters the interface between tuner.ko and the tuner sub-drivers. The v4l2 / i2c_client interface to tuner.ko remains intact. This patch adds inline functions tuner_i2c_xfer_send, and tuner_i2c_xfer_recv, to replace i2c_master_send and i2c_master_recv inside the tuner sub-drivers.
