[PATCH] doc: add firmware update links in mlx5 guide

[Dariusz Sosnowski]

> +The firmware can be updated with `mlxup

What do you think about moving these lines from "Upstream dependencies" to after:

"+  New features may be added in more recent firmwares."

in firmware subsection?

I don't think that "Upstream dependencies" is a good place for this info.
