Since the claw code calls ccwgroup_remove_ccwdev(), we need to make sure
CCWGROUP is enabled when CLAW is enabled. Otherwise we hit fun undefined
references at build time:
ERROR: "ccwgroup_remove_ccwdev" [drivers/s390/net/claw.ko] undefined!
ERROR: "ccwgroup_probe_ccwdev" [drivers/s390/net/claw.ko] undefined!
