libfdt: Detected out-of-space with fdt_finish()
At present the Python sequential-write interface can produce an error when it calls fdt_finish(), since this needs to add a terminating tag to the end of the struct section. Fix this by automatically expanding the buffer if needed. Signed-off-by: Simon Glass <sjg@chromium.org>
