device: Make device_get_binding() const correct

Browse source 
Currently passing a constant string (other than a string
literal) to device_get_binding() generates a spurious warning.
The warning is spurious because device_get_binding() does not,
nor is it ever likely to, modify its argument. To fix the
warning we modify the prototype to make clear name will never
be modified.
