Input: rohm_bu21023 - use managed devm_device_add_group 

Commit 57b8ff070f ("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
action that cleans the sysfs file when exiting the driver.
