The plan is to merge pwrctrl series to v6.20 (unless we get strong objections),
but once that happens, Qcom doesn't need this patch.

So it'd be good if you can just limit this patch to just Rockchip. Then once the
Rockchip also moves to pwrctrl, we can revert this patch (also the whole IRQ
based link up since the Root Port is not hotplug capable).
