s390x/ipl: clean up qom definitions and turn into TYPE_DEVICE
Let's move the qom definitions of the ipl device into ipl.h, replace "s390-ipl" by a proper type define, turn it into a TYPE_DEVICE and remove the unneeded class definition. Signed-off-by: David Hildenbrand <dahi@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
