dtc: Plugin and fixup support
This patch enable the generation of symbols & local fixup information
for trees compiled with the -@ (--symbols) option.
Using this patch labels in the tree and their users emit information
in __symbols__ and __local_fixups__ nodes.
The __fixups__ node make possible the dynamic resolution of phandle
references which are present in the plugin tree but lie in the
tree that are applying the overlay against.
