I guess the commit message needs a little explanation, such as:

"Because our driver assumes only one panel is PSR capable, and we
already have other PSR information on dev_priv instead of intel_dp. If
we ever support multiple PSR panels, we'll have to move struct
i915_psr to intel_dp anyway."

I've seen this patch so many times on this list that I really think we
could merge it before the others :)
