Being a specification, JSF doesn't have a end-of-life date. That's usually used to describe available (commercial) support, which is available for the products based on that spec.
The support offerings are quite numerous, so I'll just point out Jboss EAP and Oracle WebLogic.
If you're looking for an answer regarding JSF support by component toolkits, there's the Richfaces Support Matrix and I've seen that Primefaces-4 supports JSF-2.x up to the latest 2.2 release.
