[PATCH 4/6] s390: cio: make scm_bus_type const

["Ricardo B. Marliere" <ricardo@xxxxxxxxxxxx>]

Now that the driver core can properly handle constant struct bus_type,
move the scm_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
