Subject: [PATCH 11/12] Input: tsc200x-core - use managed devm_device_add_group

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 relative sysfs_remove_group and goto label.
