[PATCH 13/39] drm: don't call ->firstopen for KMS drivers

[Daniel Vetter]

It has way too much potential for driver writers to do stupid things
like delayed hw setup because the load sequence is somehow racy (e.g.
the imx driver in staging). So don't call it for modesetting drivers,
which reduces the complexity of the drm core -> driver interface a
notch.
