zorro: Make zorro_bus_type const

Since commit d492cc2573a0 ("driver core: device.h: make struct
bus_type a const *"), the driver core can properly handle constant
struct bus_type, move the zorro_bus_type variable to be a constant
structure as well, placing it into read-only memory which can not be
modified at runtime.
