In early_init_dt_scan_cpus() -> allocate_paca(), using ppc64_bolted_size() to get the limitation. Although MMU_SEGSIZE_256M is enough for boot cpu's paca, but in fact the bolted segment size may be MMU_SEGSIZE_1T. Hence moving mmu_early_init_devtree() a little earlier, and let any callers of ppc64_bolted_size() get the right value.
