Since commit fb533d0c5a ("[POWERPC] 8xx: Infrastructure code cleanup.")
immr_map() is just returning mpc8xxx_immr pointer and immr_unmap()
do nothing.
We already have parts of code that use mpc8xxx_immr directly so get rid
of immr_map() and immr_unmap() by using mpc8xxx_immr directly. And avoid
going through local pointers that hide the pointed structure.
