There is no need for a driver to individually add/create device groups,
the driver core will do it automatically for you.  Convert the elan_i2c
driver to use the dev_groups pointer instead of manually calling the
driver core to create the group and have it be cleaned up later on by
the devm core.

v2: change text based on Dmitry's review, it's not a race condition,
    it's just less code to worry about in a driver.
