[PATCH] s390: comon i/o layer

From: Utz Bacher <utz.bacher@de.ibm.com>
From: Cornelia Huck <cohuck@de.ibm.com>

Common i/o layer changes:
 - Consolidate store channel subsystem characteristics from its three
   users (css, cmf and qdio) to a single location.
 - Always use new stipd format and move creation of global path group
   to channel subsystem init function. Add dummy init_IRQ to setup.c
   and remove requestirq.c.
 - Remove bogus CHPID_LONGS define.
 - Add more magic to catch chpids coming online again without generating
   machine checks.
 - Fix check for unsolicited interrupts. Deferred cc=1 indicates a
   solicited interrupt.
 - Fix progress indication in qdio summary bytes to avoid loosing interrupts.
 - Rename console_device to console_devno to avoid naming conflict.
