Now that we can use -EPROBE_DEFER, it's no longer required to spin off the snd_hdac_i915_init into a workqueue.
Use the -EPROBE_DEFER mechanism instead, which must be returned in the probe function.
The previously added probe_early can be used for this, and we also use the newly added remove_late for unbinding afterwards.
