[PATCH v2 2/3] drm/i915: Pass intel_display to the encoder suspend/shutdown helpers

[Imre Deak <imre.deak@xxxxxxxxx>]

Pass intel_display to the encoder suspend/shutdown helpers instead of
drm_i915_private for better isolation.

v2: Pass intel_display to HAS_DISPLAY() as well, update commit log
    accordingly. (Jani)
