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.

  s390-tools part.
  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
