The shutdown function can be called when the display is already
unprepared. For example during reboot this trigger a kernel
backlog. Calling the drm_panel_unprepare, allow us to avoid
to trigger the kernel warning

It's not obviovus if shutdown can be dropped or this problem depends
on the display stack as it is implmented. More feedback is required
here
