MIPS: zboot: put appended dtb into a section
This will make a separated section for dtb appear in ELF, and we can
then use objcopy to patch a dtb into vmlinuz when RAW_APPENDED_DTB
is set in kernel config.
command to patch a dtb:
objcopy --set-section-flags=.appended_dtb=alloc,contents \
--update-section=.appended_dtb=<target>.dtb vmlinuz
