Change subject: [RFC] util/sconfig: Drop topology from early static tree
......................................................................

Patch Set 7:
> having config data early (bootblock, etc) but remove the bloat from the full device tree. In many of these scenarios we don't need the device itself. We just need the config object.

We could emit references to the config objects, the same as for
device nodes. e.g. like this:

DEVTREE_CONST struct northbridge_intel_gm45_config *const __pci_0_00_0_chip_info = northbridge_intel_gm45_info_1;

Then `__pci_0_00_0->chip_info` would become `__pci_0_00_0_chip_info`
and GC could take care of the device node if it's not referenced
otherwise.
