[PATCH 18/22] Input: rohm_bu21023 - use device core to create driver-specific device attributes

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

Instead of creating driver-specific device attributes with
devm_device_add_group() have device core do this by setting up dev_groups
pointer in the driver structure.
