With the upcoming changes for i915/Xe driver relying on the -EPROBE_DEFER mechanism, we need to have a first pass of the probe which cannot be pushed to a workqueue. Introduce 2 new optional callbacks. probe_early is called before the workqueue runs. remove_late may be called from the workqueue if load is unsuccesful, but will otherwise be called on module unload.

This can be used as a first approximation on whether i915 will be available. It's safe to use as this is only built when CONFIG_SND_HDA_I915 is selected by CONFIG_I915. It's not completely fool proof, as you can boot with "nomodeset i915.modeset=3D1" to make i915 load regardless, or use "i915.force_probe=3D!*" to never load i915, but the common case of booting with nomodeset to disable all GPU drivers this will work as intended. Because of this, we add an extra module parameter, snd_hda_core.gpu_bind that can be used to signal users intent. -1 follows nomodeset, 0 disables binding, 1 forces wait/-EPROBE_DEFER on binding.
