Subject: [PATCH 15/15] kbuild: use .init.rodata section unconditionally for cmd_wrap_S_dtb

Boot DTBs are now wrapped and compiled in scripts/Makefile.vmlinux.

The cmd_wrap_S_dtb rule in scripts/Makefile.dtbs is now only used
for generic purposes, so the .init.rodata section should be used
unconditionally.
