dma-debug: make dma_debug_add_bus take a const pointer
The driver core now can handle a const struct bus_type pointer, and the dma_debug_add_bus() call just passes on the pointer give to it to the driver core, so make this pointer const as well to allow everyone to use read-only struct bus_type pointers going forward.
