Subject: drm/omap: Init fbdev emulation only when we have displays
Git-commit: da77772172059e609ef5135881df55e3e6c5c808
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Do not try to init the fbdev if either num_crtcs or num_connectors is 0.
In this case we do not have display so the fbdev init would fail anyways.
