fdt/wrappers: Introduce code to find UART DT node
The stdout-path property in the /chosen node of a DTB points to a device node, which is used for boot console output. On most (if not all) ARM based platforms this is the debug UART. The ST platform code contains a function to parse this property and chase down eventual aliases to learn the node offset of this UART node. Introduce a slightly more generalised version of this ST platform function in the generic fdt_wrappers code. This will be useful for other platforms as well.
