There is no implication whatsoever I've seen of it being a prequel, and I'm sure other people have already said what can be said on that front. What I will say, is that it's hinted that Drangleic was once Lordran, and there are a number of implications to suggest this, such as dialogue, item descriptions, and obviously the inclusion of the Old Dragonslayer. In particular, Straid's dialogue, as well as Chloanne's, the Lingering Dragoncrest ring description, multiple mentions of a war with the giants, etc.
