## Summary

libfdt: Replace deprecated 0-length arrays with proper flexible arrays

Replace the 0-length arrays in structures with proper flexible
arrays. This will avoid warnings when building under GCC 13 with
-fstrict-flex-arrays, which the Linux kernel will be doing soon:

In file included from ../lib/fdt_ro.c:2:
