OMAPDSS: Fix crash with DT boot
When booting with DT, there's a crash when omapfb is probed. This is caused by the fact that omapdss+DT is not yet supported, and thus omapdss is not probed at all. On the other hand, omapfb is always probed. When omapfb tries to use omapdss, there's a NULL pointer dereference crash. The same error should most likely happen with omapdrm and omap_vout also. To fix this, add an "initialized" state to omapdss. When omapdss has been probed, it's marked as initialized. omapfb, omapdrm and omap_vout check this state when they are probed to see that omapdss is actually there.
