The signature check on config node is broken on fit with padding. To compute the signature for config node, u-boot compute the signature on all properties of requested node for this config, except for the property "data". But, when padding is used for binary in a fit, there isn't a property "data" but two properties: "data-offset" and "data-size". So to fix the check of signature, we also dont use the properties "data-offset" and "data-size" when checking the signature on config node.
