Input: edt-ft5x06 - use managed devm_device_add_group

Commit 57b8ff07 ("driver core: add devm_device_add_group() and
friends") has added 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.
