How about adding a soc specific (wrapper) driver for the memory controller, which
could use the PCI id and trigger EDAC and PMU drivers (based on what is
selected by configs)  ?  

Sounds good to me. Is there a driver that already does this?

Sounds like a classic MFD (multifunction device). There are quite a few pci
devices to be found under drivers/mfd/ than may provide some inspiration.

I've looked into that before, from what I recall it did not fit my use
case. After all these are multi-fn devices.
