Driver core: add device_type to struct device
This allows us to add type specific attributes, uevent vars and
release funtions.
A subsystem can carry different types of devices like the "block"
subsys has disks and partitions. Both types create a different set
of attributes, but belong to the same subsystem.
This corresponds to the low level objects:
kobject -> device (object/device data)
kobj_type -> device_type (type of object/device we are embedded in)
kset -> class/bus (list of objects/devices of a subsystem)
