MIPS: Ensure ELF appended dtb is relocated
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.
