Explicitly loading i915 becomes a problem when upstreaming the new intel driver
for Tiger Lake and higher graphics (xe). By loading i915, it doesn't wait for
driver load of xe, and will fail completely before it loads.
-EPROBE_DEFER has to be returned before any device is created in probe(),
otherwise the removal of the device will cause EPROBE_DEFER to try again
in an infinite loop.
The conversion is done in gradual steps. First I add an argument to
snd_hdac_i915_init to allow for -EPROBE_DEFER so I can convert each driver
separately. Then I convert each driver to move snd_hdac_i915_init out of the
workqueue. Finally I drop the ability to choose modprobe behavior after the
last user is converted.
Compared to previous version, I added the patch
"ASoC: SOF: Intel: Fix error handling in hda_init()"
