soc/apollolake: Use simpler macros for the northbridge PCI device

The NB_DEV_ROOT macro, is almost unreadable, as it depends on other
    stringified macros, and acts differently depending on the coreboot
    stage. For ramstage, it also hides a function call.
    Rewrite the macro in terms of more basic and readable macros.
