Well, I don't understand why moving this code around fixes a problem.
After all, if PCI is enabled, then presumably common-pci.c will always
be built and run - it has to be for the PCI bus to be probed.

Oh, are you trying to use the platform notify callback to set the
DMA mask on statically defined platform devices?  No, don't do that,
initialise it in the declarations instead.
