[RFC 2/5] [media] dt: bindings: Update binding documentation for sunxi IR controller

[Philipp Rossak <embed3d-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

This patch updates documentation for Device-Tree bindings for sunxi IR
controller and adds the new requiered property for the base clock frequency.
