drm/i915: Introduce struct intel_wakeref
For controlling runtime pm of the GT and engines, we would like to have
a callback to do extra work the first time we wake up and the last time
we drop the wakeref. This first/last access needs serialisation and so
we encompass a mutex with the regular intel_wakeref_t tracker.
v2: Drop the _once naming and report the errors.
