[PATCH] intel_th: make intel_th_bus_type constant

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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