i2c: Convert remaining new-style drivers to use module aliasing
Update all the remaining new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. Note that the tuner driver is a bit quirky at the moment, as it overwrites i2c_client.name with arbitrary strings. We write "tuner" back on remove, to make sure that driver cycling will work properly, but there may still be troublesome corner cases. Signed-off-by: Jean Delvare <khali@linux-fr.org>
