Is it any unit with a psychic power? Or is it a special rule that says Psyker?

Some units have a special rule with a descriptor of "Psycher" but some things just have a psychic ability.

So both would qualify?

I know Inquisitors have the rule because you don't have to buy them any psychic powers - the rule is there to say that they count as psykers even if they have not been given psychic powers and/or wargear.

So to answer your question, yes.

An important thing to be aware of is that some models have abilities that behave like psychic powers, but are not. Chaos Daemons are one example, Necrons/C'tan are another. Their abilities look magical but trigger like war gear, and can't be affected by things like Psychic Hoods or Shadow in the Warp, etc.
