  1. ASoC: SOF: core: add 'no_wq' probe callback 

    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 a new optional
callback.

Note that instead of probe_no_wq/probe we could have use a more
self-explanatory naming such as probe/probe_wq_allowed, but that would
have been a very intrusive change.

  2. ASoC: SOF: Intel: hda: start splitting the probe 

    This patch moves the initial parts of the probe to the probe_no_wq()
callback, which provides a much faster decision on whether the SOF
driver shall deal with a specific platform or yield to other Intel
drivers.

FIXME:
This is a limited functionality change, the bigger change is to move
the i915/Xe initialization to the probe_no_wq().
