util/sconfig: Declare the repeated devicetree storage
With DEVTREE_EARLY we could create incomplete device objects with topology links removed to reduce footprint for bootblock. Declare everything with 'static __unused DEVTREE_CONST' to avoid compiler errors and to not expose unusable device object names to global scope.
