The current code assumes "foo-bar" must always be compatible with a node

The "case" part is also wrong according to Open Firmware, but it's more
likely to have drivers and/or device trees depending on it, and thus
needs to be handled more carefully.

After wasting about an hour with git bisect, I finally realized that
this patch "caught" an error in the walnut patches I'm working on (by
making it not boot). So thanks!
