pm support is going to be removed (for s390 in general and) for
net/iucv/iucv.c with this net-next patch:

commit 4b32f86bf1673acb16441dd55d7b325609f54897
Author: Julian Wiedmann <jwi@linux.ibm.com>
Date:   Tue May 19 21:10:08 2020 +0200

    net/iucv: remove pm support
    
    commit 394216275c7d ("s390: remove broken hibernate / power management support")
    removed support for ARCH_HIBERNATION_POSSIBLE from s390.
    
    So drop the unused pm ops from the s390-only iucv bus driver.
