As you say these numbers could be used by drivers on non-DT enabled
platforms, but for that this include file should be in
include/linux/interconnect. That said, there are no such Qualcomm
platforms, so these numbers will only ever be used internally in the
qcs404.c provider, so it would be better to just define them in that
file - to remove the risk of confusion.

I had missed that you implemented support for xlating NoC-specific ids,
so this makes sense now, nice. I presume we won't ever include files in
a way where these defines collide - so this looks good.
