Applied to imx-drm/next, thank you.

This looks about right to me. We currently don't call the
fbdev suspend/resume notifiers at all. The correct call
would be drm_fbdev_cma_set_suspend_unlocked instead of
drm_fb_helper_set_suspend_unlocked, though.
Since drm_fb_cma_fbdev_init registers its fb_helper with the
drm_device via drm_fb_helper_init, both (currently) do exactly
the same thing.
