I do not see anything on Northstar that needs it. I think
pcie-iproc-platform is the front end for the iProc SoCs that have no
bcma bus.

None that I can find. Neither symbol depends on the other, no in-tree
defconfig sets either one, and multi_v7_defconfig gets both from their
defaults. OpenWrt builds only the BCMA one. The one use of the
platform driver on Northstar I know of is Rafał's: 767012397976 says
it was tested with it on BCM47094, and his test in the thread on the
axi ranges ran both drivers on his board. The platform driver
enumerated the two BCM4366 devices on its own:

I have not looked outside the tree.
