drm/i915: Re-register PMIC bus access notifier on runtime resume

Browse source

commit 294cf1af8c upstream.

intel_uncore_suspend() unregisters the uncore code's PMIC bus access
notifier and gets called on both normal and runtime suspend.

intel_uncore_resume_early() re-registers the notifier, but only on
normal resume. Add a new intel_uncore_runtime_resume() function which
only re-registers the notifier and call that on runtime resume.
