drm/imx: kill firstopen callback
This thing seems to do some kind of delayed setup. Really, real kms drivers shouldn't do that at all. Either stuff needs to be dynamically hotplugged or the driver setup sequence needs to be fixed. This patch here just moves the setup at the very end of the driver load callback, with the locking adjusted accordingly. v2: Also move the corresponding put from ->lastclose to ->unload.
