[qemu-s390x] [PATCH v5 1/6] linux-headers: linux header updates for AP support

[Tony Krowiak]

Updates the linux header files in preparation for introduction
of the VFIO AP device:

* Added a feature ID to indicate AP facilities are installed

* Added a device attribute to the KVM_S390_VM_CRYPTO group to
  indicate whether AP instructions are to be interpreted

* Added VFIO device information for AP devices
