Subject: drm: omapdrm: panel-dpi: Remove unneeded check for OF node
Git-commit: afed19e46eec6f4ccc5690ce7999b99b13df3ba8
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

As non-DT booting is no longer supported, the only way to instantiate
the device is through an OF node, which is guaranteed to be present.
Remove the unneeded check.
