[PATCH 06/12] Input: elants_i2c - use managed devm_device_add_group

[Andi Shyti]

Commit 57b8ff070f98 ("driver core: add devm_device_add_group()
and friends") has added the the managed version for creating
sysfs group files.

Use devm_device_add_group instead of sysfs_create_group and
remove the action that cleans the sysfs file when exiting the
driver.
