of: make set_node_proc_entry private to proc_devtree.c

We only need set_node_proc_entry in proc_devtree.c, so move it there.

This fixes the !HAVE_ARCH_DEVTREE_FIXUPS build, as we can't make make
the definition in linux/of.h conditional on this #define (definitions in
asm/prom.h can't be exposed to linux/of.h, due to the enforced #include
ordering).
