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.

of/promtree: add package-to-path support to pdt

package-to-path is a PROM function which tells us the real (full) name of the
node. This provides a hook for that in the prom ops struct, and makes use
of it in the pdt code when attempting to determine a node's name. If the
hook is available, try using it (falling back to looking at the "name"
property if it fails).

of/promtree: no longer call prom_ functions directly; use an ops structure

Rather than assuming an architecture defines prom_getchild and friends,
define an ops struct with hooks for the various prom functions that
pdt.c needs. This ops struct is filled in by the
arch-(and sometimes firmware-)specific code, and passed to
of_pdt_build_devicetree.

Update sparc code to define the ops struct as well.
