[media] media: Initialize the media core with subsys_initcall()
Media-related drivers living outside drivers/media/ (such as the UVC gadget driver in drivers/usb/gadget/) rely on the media core being initialized before they're probed. As drivers/usb/ is linked before drivers/media/, this is currently not the case and will lead to crashes if the drivers are not compiled as modules. Register media_devnode_init() as a subsys_initcall() instead of module_init() to fix this.
