s390 vfio-ccw: Add bootindex property and IPLB data

Browse source 
Add bootindex property and iplb data for vfio-ccw devices. This allows us to
forward boot information into the bios for vfio-ccw devices.

Refactor s390_get_ccw_device() to return device type. This prevents us from
having to use messy casting logic in several places.
