Now that we can use -EPROBE_DEFER, it's no longer required to spin off
the snd_hdac_i915_init into a workqueue. It's likely the whole workqueue
can be destroyed, but I don't have the means to test this.

Removing the workqueue would simplify init even further, but is left
as exercise for the reviewer.
