[PATCH v7 2/6] drm/i915/psr: Add intel_psr_use_trans_push to query if TRANS_PUSH is used

[Jouni Högander]

This is a preparation to start using trans push as a PSR "Frame Change"
event. It adds intel_psr_use_trans_push placeholder which return false for
now until we have everything in place.

v2:
  - modify commit message
  - add TODO
