Subject: [PATCH v3 8/9] ASoC: SOF: Intel: Move binding to display driver outside of deferred probe

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.
