Bug description:
[Impact]
* HW enablement
* Kernel supports alternate zcrypt device drivers, hence lszcrypt (an information tool) should show if a driver is bound, and which one, given that it is no longer unambiguous.
[Test Case]
* Run lszcrypt, ensure it shows info about crypto cards, and a driver
name.
$ lszcrypt -V
CARD.DOMAIN TYPE MODE STATUS REQUESTS PENDING HWTYPE QDEPTH FUNCTIONS DRIVER
--------------------------------------------------------------------------------------------
01 CEX5C CCA-Coproc online 1 0 11 08 ---D----- cex4card
01.0001 CEX5C CCA-Coproc online 1 0 11 08 ---D----- cex4queue
[Regression Potential]
* Changes are to an informational lszcrypt tool, output of which is
now chnaged, but is not typically parsed in an automated fashion.
(automation is usually done with lszdev/chzdev commands)
[Other Info]
* Original bug report:
With the introduction of KVM crypto virtualization the driver bound to an AP queue device is no longer unique determined.
This feature provides a deterministic hot plugging semantics of AP queues that may be bound to multiple drivers.
In particular it enables to configure an AP queue (APQN) as being bound to a particular driver even if the associate HW gets intermittently lost and reconnected.

Backport from 2.7.0 to 2.6.0
Git commit: for s390-tools 2.7.0

lszcrypt: support for alternate zcrypt device drivers
It needs to be applied to 2.6.0 for Ubuntu 18.10, which will apply
seamlessly
