uninorth: remove token register from uninorth device

Browse source 
>From observation of various OS sources it can be seen that the token register
introduced in 4e46dcdbd3 "PPC: Newworld: Add uninorth token register" is not
required, since the only register currently implemented is the uninorth hardware
version which is read-only.

Remove the token register implementation and instead return the uninorth
version corresponding to the hardware.
