Tony Krowiak c5cd17afdd s390x/cpumodel: Set up CPU model for AP device support 
A new CPU model feature and two new CPU model facilities are
introduced to support AP devices for a KVM guest.

CPU model features:

1. The S390_FEAT_AP CPU model feature indicates whether AP
   instructions are available to the guest. This feature will
   be enabled only if the AP instructions are available on the
   linux host as determined by the availability of the
   KVM_S390_VM_CRYPTO_ENABLE_APIE VM attribute which is exposed
   by KVM only if the AP instructions are available on the
   host.

   This feature must be turned on from userspace to execute AP
   instructions on the KVM guest. The QEMU command line to turn
   this feature on looks something like this:

	qemu-system-s390x ... -cpu xxx,ap=on ...

   This feature will be supported for zEC12 and newer CPU models.
   The feature will not be supported for older models because
   there are few older systems on which to test and the older
   crypto cards will be going out of service in the relatively
   near future.

CPU model facilities:

1. The S390_FEAT_AP_QUERY_CONFIG_INFO feature indicates whether the
   AP Query Configuration Information (QCI) facility is available
   to the guest as determined by whether the facility is available
   on the host. This feature will be exposed by KVM only if the
   QCI facility is installed on the host.

2. The S390_FEAT_AP_FACILITY_TEST feature indicates whether the AP
   Facility Test (APFT) facility is available to the guest as
   determined by whether the facility is available on the host.
   This feature will be exposed by KVM only if APFT is installed
   on the host.
