[new uImage] New uImage low-level API
Add FDT-based functions for handling new format component images,
configurations, node operations, property get/set, etc.
fit_ - routines handling global new format uImage operations
like get/set top level property, process all nodes, etc.
fit_image_ - routines handling component images subnodes
fit_conf_ - routines handling configurations node
