drm/i915: Track the wakeref used to initialise display power domains
On module load and unload, we grab the POWER_DOMAIN_INIT powerwells and
transfer them to the runtime-pm code. We can use our wakeref tracking to
verify that the wakeref is indeed passed from init to enable, and
disable to fini; and across suspend.
