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 device attributes to the KVM_S390_VM_CRYPTO group
to indicate whether AP instructions are to be interpreted
* Added VFIO device information for AP devices

Guess that's a leftover. But should be fixed automatically by proper
header sync later.
Oops
