Starting with kernel 5.17 the kernel supports the builtin privacy screens
built into the LCD panel of some new laptop models.
This means that the drm drivers will now return -EPROBE_DEFER from their
probe() method on models with a builtin privacy screen when the privacy
screen provider driver has not been loaded yet.
Make dracut add the privacy screen providing drivers to the initrd
(when necessary for hostmode=yes), so that drm drivers on affected
drivers can probe() successfully.
