ASoC: SOF: core: Add probe_early and remove_late callbacks

Browse source

The existing DSP probe may be handled in a workqueue to allow for
extra time, typically for the i915 request_module and HDAudio codec
handling.

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.
