powerpc: Add del_node() for early boot code to prune inapplicable devices.
Some platforms have variants that can share most of a flat device tree but need a few devices selectively pruned at boot time. This adds del_node() to ops.h to allow access to the existing fdt_del_node(). Signed-off-by: Mike Ditto <mditto@consentry.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
