Enabling the display would be nice but for some quite long time we had
issues with DRM on Exynos. exynos_defconfig has it enabled and most of
boards boot fine with it. Exception is Arndale 5250:
[ 1.630290] [drm:exynos_dp_bind] *ERROR* failed: of_get_videomode() : -22
[ 1.637071] exynos-drm exynos-drm: failed to bind
145b0000.dp-controller (ops exynos_dp_ops): -22
[ 1.646504] exynos-drm exynos-drm: master bind failed: -22
[ 1.651391] exynos-drm: probe of exynos-drm failed with error -22

Anyway it is not like I am against it... just wondering. On the other
hand enabling it could help in early detection of errors.
