w1: slaves: w1_ds2431: convert to use w1_family_ops.groups
This moves the sysfs file creation/removal to the w1 core by using the .groups field, saving code in the slave driver. Acked-by: Evgeniy Polyakov <zbr@ioremap.net> Cc: Alexander Stein <alexander.stein@informatik.tu-chemnitz.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
