Removed some nonused fdt functions and moved fdt_find_and_setprop out of libfdt
Removed: fdt_node_is_compatible fdt_find_node_by_type fdt_find_compatible_node To ease merge of newer libfdt as we aren't using them anywhere at this time. Also moved fdt_find_and_setprop out of libfdt into fdt_support.c for the same reason. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
