ALSA: hda: i915: Add an allow_modprobe argument to snd_hdac_i915_init
Xe is a new GPU driver that re-uses the display (and sound) code from
i915. It's no longer possible to load i915, as the GPU can be driven
by the xe driver instead.
The new behavior will return -EPROBE_DEFER, and wait for a compatible
driver to be loaded instead of modprobing i915.
Converting all drivers at the same time is a lot of work, instead we
will convert each user one by one.
