Subject: [RFC 19/19] s390/facilities: enable AP facilities needed by guest

Sets up the following facilities bits to enable the specified AP
facilities for the guest VM:
    * STFLE.12: Enables the AP Query Configuration Information
                facility. The AP bus running in the guest uses
                the information returned from this instruction
                to configure AP adapters and domains for the
                guest machine.
    * STFLE.15: Indicates the AP facilities test is available.
                The AP bus running in the guest uses the
                information.
