From: Roderick Colenbrander <roderick.colenbrander@xxxxxxxx>
The DS4 dongle reports fw_version and hw_version as 0 when no actual
DS4 is connected to it. This prevents cleaning up sysfs nodes upon
device remove.
This patch decouples sysfs cleanup from the fw_version and hw_version
values by introducing boolean values.
