From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com
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.
This is a limited functionality change, the bigger change is to move the i915/Xe initialization to the probe_no_wq().
