MIPS: Ensure ELF appended dtb is relocated
commit 3f0a53bc6482fb09770982a8447981260ea258dc upstream.
This fixes booting with the combination of CONFIG_RELOCATABLE=y
and CONFIG_MIPS_ELF_APPENDED_DTB=y.
Sections that appear after the relocation table are not relocated
on system boot (except .bss, which has special handling).
With CONFIG_MIPS_ELF_APPENDED_DTB, the dtb is part of the
vmlinux ELF, so it must be relocated together with everything else.
Fixes: 069fd766271d ("MIPS: Reserve space for relocation table")
