add fit_info command to the host tools. This command prints the name, offset and the len from a property from a node in a fit file. This info can be used to extract a properties data with linux tools, for example "dd". Signed-off-by: Heiko Schocher <hs@denx.de> Acked-by: Simon Glass <sjg@chromium.org>
