s390/zcrypt: introduce state machine for the AP bus Replace the two fields 'unregistered' and 'reset' with a device state with 5 possible values. Introduce two events for the AP devices, device poll and device timeout. With the state machine it is easier to deal with device initialization and suspend/resume. Device polling is simpler as well, the arkane 'flags' passing is gone. Reviewd-by: Ingo Tuchscherer <ingo.tuchscherer@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
