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.
