This allows to catch more generic cases of code needing patches than doing it in smp_prepare_boot_cpu() and also makes it actually work if CONFIG_SMP is disabled for whatever reason. The position is chosen mainly as it is before the actual soc early init runs but also already allows accessing the devicetree via fdt_* functions.
