hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0 (part 2)

hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0 (part 2)

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

This is a follow up to commit d8a66f3621c2 ("hwmon: Drop explicit
initialization of struct i2c_device_id::driver_data to 0") which I
created before identifying a few corner cases in my conversion script.
