Git-commit: d6cae4aa30ce551dfa2872f793f64d39719da6b7
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Normally this is called on a modeset, but the call is missing when
we inherit the mode from the BIOS, so make sure it's called somewhere
in hardware readout.
Changes since v1:
- Unconditionally call intel_opregion_notify_encoder. (Ville)
