Since commit d492cc2573 ("driver core: device.h: make struct
bus_type a const *"), the driver core can properly handle constant
struct bus_type, move the host1x_context_device_bus_type variable
to be a constant structure as well, placing it into read-only memory
which can not be modified at runtime.
