I really dislike the (ab)use of "REMAP" for this. DM is and always has
been about remapping IO. Would prefer DM_DEV_INTERPOSE_CMD

Similarly, all places documenting "remap" or variables with "remap"
changed to "interpose".

Also, any chance you'd be open to putting all these interposer specific
changes in dm-interposer.[ch] ?
(the various internal structs for DM core _should_ be available via dm-core.h)
