[PATCH] powerpc: Remove device_node addrs/n_addr
The pre-parsed addrs/n_addrs fields in struct device_node are finally gone. Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code. This patch also fixes a bunch of drivers to use the new code instead, so that at least pmac32, pseries, iseries and g5 defconfigs build.
