Commit 5590f3196b29 ("drivers/core/of: Add symlink to device-tree from
devices with an OF node") adds the symlink `of_node` for each device
pointing to it's device tree node while creating/initialising it.
However the devicetree sysfs is created and setup in of_init which is
executed at core_initcall level. For all the devices created before
of_init, the following error is thrown:
"Error -2(-ENOENT) creating of_node link"
Like many other components in driver model, initialize the sysfs support
for OF/devicetree from driver_init so that it's ready before any devices
are created.

Looks like we still have conflict even though the one I pointed was in
bootwrapper. Kbuilder reported the following build error:
drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadowof.c:45:1: error:
conflicting types for 'of_init'
of_init(struct nvkm_bios *bios, const char *name)

Sorry I couldn't catch this with any ppc defconfigs. Please ignore this
version, will repost updated one soon renaming to of_core_init
as initially discussed.
