s390/ap: Support AP card SCLP config and deconfig operations
BugLink: https://bugs.launchpad.net/bugs/1939618
Support SCLP AP adapter config and deconfig operations:
The sysfs deconfig attribute /sys/devices/ap/cardxx/deconfig
for each AP card is now read-write. Writing in a '1' triggers
a synchronous SCLP request to configure the adapter, writing
in a '0' sends a synchronous SCLP deconfigure request.
