[Qemu-devel] [PATCH 16/23] s390/sclp: move sclp_service_interrupt into the sclp device

[Cornelia Huck <cornelia.huck@de.ibm.com>]

From: David Hildenbrand <dahi@linux.vnet.ibm.com>

Let's make that function a method of the new sclp device, keeping
the wrapper for existing users.

We can now let go of get_event_facility().
