Factor out a few commonly duplicated functions from northbridge.c.
The following functions are moved to devices/device_util.c:
- ram_resource()
- tolm_test()
- find_pci_tolm()
There are only two tolm_test() / find_pci_tolm() which differ from the
defaults, one of them can easily be eliminated in a follow-up patch,
maybe even both, but for now keep it simple and only eliminate the majority.
