[S390] qdio: new qdio driver.
List of major changes: - split qdio driver into several files - seperation of thin interrupt code - improved handling for multiple thin interrupt devices - inbound and outbound processing now always runs in tasklet context - significant less tasklet schedules per interrupt needed - merged qebsm with non-qebsm handling - cleanup qdio interface and added kerneldoc - coding style Reviewed-by: Cornelia Huck <cornelia.huck@de.ibm.com> Reviewed-by: Utz Bacher <utz.bacher@de.ibm.com> Reviewed-by: Ursula Braun <braunu@de.ibm.com> Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
