of: Eliminate of_allnodes list
The device tree structure is composed of two lists; the 'allnodes' list which is a singly linked list containing every node in the tree, and the child->parent structure where each parent node has a singly linked list of children. All of the data in the allnodes list can be easily reproduced with the parent-child lists, so of_allnodes is actually unnecessary. Remove it entirely which saves a bit of memory and simplifies the data structure quite a lot.
