The sysfs logic already creates a list of groups for the device, so add
the sdw_slave_dev_attr_group group to that list instead of having to do
a two-step process of adding a group list and then an individual group.

This is a step on the way to moving all of the sysfs attribute handling
into the default driver core attribute group logic so that the soundwire
core does not have to do any of it manually.

Hey Greg,

DO you have a v2 for this, or if you are too busy I can update the
patchset...
