update Bender.yml by using flist and vendor deps

[joennlae]

This is a version of Bender.yml that works. However, it does only use the vendored in IPs. I know kind of defying the purpose of bender but still useful for a bender pipeline when cva6 is included.

Hi @joennlae, I opened #7 on your and @Vyeow's behalf. Feel free to modify it. I would propose using this thread for discussions on updating Bender.yml to avoid fragmentation.

Regarding this change: I think larger projects with CVA6 as a dependency might not want to be forced to use the vendored dependencies of common cells etc. But for a standalone instantiation, this might be favourable. My proposal from #7 stands: Add a target ariane_soc or similar that would include these files (however, this might require conditional dependencies).

Hi, @niwis. I am aware of #7. That is also why this pull request is against the bender branch and not against main. I get your point which totally makes sense.

I tried to make it work with bendered deps, but I got duplicate module declarations. Due to nonconforming versions. Which cannot be easily fixed because the others are vendored.

But I understand that we need to have the possibility. So do you want to have the ariane_soc target as the one using the vendored versions?

[niwis]

I don't have any strong opinions on this. My main question is: is this change compatible with a system like Cheshire, which has common_cells as a dependency?
