Remove out of date info

[linimon]

Remove a reference that is over a decade out of date.

@dbaio or someone from a translation team, correct me if I'm wrong, but IIRC that file is automatically generated from documentation/content/en/books/arch-handbook/driverbasics/_index.adoc, which is the one to modify instead, and still has that reference as I'm writing this.

@pauamma correct, the .adoc file needs to be updated

I'm gonna make the change and push it to the repo. I'll give the credit to linimon@ :)
