drm/i915: add poweroff_late handler

ideak · danvet · commit da2bc1b9db33 · 2014-10-24T16:34:20.000+02:00
The suspend_late handler saves some registers and powers off the device,
so it doesn't have a big overhead. Calling it at S4 poweroff_late time
makes the power off handling identical to the S3 suspend and S4 freeze
handling, so do this for consistency.
