[PATCH] dt-bindings: display/msm: dp-controller: allow eDP for X1E8 and SA8775P

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

On Qualcomm SA8775P and X1E80100 the DP controller might be driving
either a DisplayPort or a eDP sink (depending on the PHY that is tied to
the controller). Reflect that in the schema.

Jessica, your X1E8 patch also triggers warnings for several X1E8-based
laptops. Please include this patch into the series (either separately
or, better, by squashing into your first patch).
