Harald Freudenberger ebf95e8846 s390/ap,zcrypt,vfio: introduce and use ap_queue_status_reg union
Introduce a new ap queue status register wrapper union to access register
wide values. So the inline assembler only sees register wide values but the
surrounding code may use a more structured view of the same value and a
reader of the code (and the compiler) gets a clear understanding about the
mapping between fields and register values.

All the changes to access the ap queue status are local to the inline
functions within ap.h. However, the struct ap_qirq_ctrl has been replaces
by a union for same reason and this needed slight adaptions in the calling
code.
