When trying to connect the device with the driver through
device-tree it is not working. The of_device_id is defined in
cs42xx8.c but is not correctly included in cs42xx8-i2c.c.

Move of_device_id table to cs42xx8-i2c.c. Get cs42xx8_driver_data
in cs42xx8_i2c_probe() and pass as argument to cs42xx8_probe(). Move
error check if no driver data found to cs42xx8_i2c_probe().
