[PATCH v5 08/14] riscv: move boot alternatives to a slightly earlier position

[Heiko Stuebner <heiko@sntech.de>]

Move the application of boot alternatives to soc_early_init().
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.
