hw/s390x/s390-pci-bus: Convert sysbus init function to realize function

Browse Source 
The SysBusDeviceClass->init() interface is considered as a legacy interface
and there are currently some efforts going on to get rid of it. Thus let's
convert the init function in the s390x code to realize() instead.
