fdt: Update functions which write to an FDT to return -ENOSPC
When writing values into an FDT it is possible that there will be insufficient space. If the caller gets a useful error then it can potentially deal with the situation. Adjust these functions to return -ENOSPC when the FDT is full. Signed-off-by: Simon Glass <sjg@chromium.org>
