[2/4] drm/i915: Add a dummy notrace version of intel_de_read64_2x32

Commit Message

Sripada, Radhakrishna June 13, 2023, 9:52 p.m. UTC

intel_de_read64_2x32 and hence intel_uncore_read64_2x32 do not use any
of the tracing api's. It is however important to distinguish between the
tracing and non tracing versions to avoid nesting of tracing events.
