s390x/pci: separate s390_sclp_configure function
Split s390_sclp_configure() into separate functions for sclp configuring and deconfiguring in order to make the code more readable. Signed-off-by: Yi Min Zhao <zyimin@linux.vnet.ibm.com> Reviewed-by: Pierre Morel <pmorel@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
