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

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

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