tc: make tc_bus_type const 



Since commit d492cc25 ("driver core: device.h: make struct
bus_type a const *"), the driver core can properly handle constant
struct bus_type, move the tc_bus_type variable to be a constant
structure as well, placing it into read-only memory which can not be
modified at runtime.
