[PATCH 05/11] vmlinux.lds.h: Preserve DTB sections from being discarded after init

[Andrea della Porta]

The special section .dtb.init.rodata contains dtb and dtbo compiled
as objects inside the kernel and ends up in .init.data sectiion that
will be discarded early after the init phase. This is a problem for
builtin drivers that apply dtb overlay at runtime since this happens
later (e.g. during bus enumeration) and also for modules that should
be able to do it dynamically during runtime.
Move the dtb section to .data.
