Currently, if any step of the DTB patching process fails, the whole
process is aborted. However, this causes some problems:
- If any step modifies the DTB (including fdt_open_into), the dcache
must still be cleaned, even if some later step fails.
- The DTB may need changes in multiple places; if one patch fails (for
example due to missing nodes), we should still apply other patches.
- Similarly, if some patch fails, we should still run fdt_pack to
clean up after ourselves.
