drm/i915/dp: Sanity check eDP existence

Some hardware claims to have both an LVDS panel and an eDP output.
Whilst this may be true in a rare case, more often it is just broken
hardware. If we see an eDP device we know that it must be connected and
so we can confirm its existence with a simple probe.
