libfdt: Add fdt_path_offset_namelen()
Properties may contain path names which are not NUL-terminated.
For example, the 'stdout-path' property allows the form 'path:options',
where the ':' character terminates the path specifier.
Allow these path names to be used in-place for path descending;
add fdt_path_offset_namelen(), which limits the path name to 'namelen'
characters.
Reimplement fdt_path_offset() as a trivial wrapper.
