riscv: nx25: Enable distro boot

Browse source 
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.
