driver core: make the bus_type in struct device_driver constant

Browse Source 
The pointer to struct bus_type in struct device_driver should only be
pointing to something that can never change now that the driver core has
fixed up the previously writable fields.  So mark it as a constant
pointer to enforce this and move forward with the goal of moving
bus_type into read-only memory.
