But not within kirkwood_mpp_restore(), right? So an mpp_ctrl array would be 
implicitly casted from u32* to const u32*.

so we would have the following declarations:
 kirkwood_mpp_restore(const u32 *mpp_list)
 kirkwood_mpp_conf(const u32 *mpp_list)
 kirkwood_mpp_save(u32 *mpp_list)

where only the latter modifies mpp_list.
