siox: make siox_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 siox_bus_type variable to be a constant structure as
well, placing it into read-only memory which can not be modified at
runtime.
