[U-Boot] [PATCH 7/8] riscv: nx25: Enable distro boot

[Alexander Graf <agraf@suse.de>]

Distro boot allows for a common boot path on systems that allow distributions
to easily boot from a default configuration.

This patch enables distro boot for the nx25-ae250. Hopefully this can serve
as a good example for new boards, so they enable it as well.
