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.
