How many eDP are you planning to allow on the system? We already have
precedence for the presumption of a single (integrated) panel on a device,
maybe we can add the logic there (i.e. stash a back pointer in this case)?
We could then also do a debugfs/i915_panel_info where we can inspect
various details normally associated with the panels (PSR status, backlight
interface, eDP vs LVDS, etc).
