drm/i915: Call intel_opregion_notify_encoder in intel_sanitize_encoder, v2.

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)
