When a PME wake happens due to a SoundWire wake, we currently clear all WAKESTS bits during the resume operation initiated by the PCI subsystem. As a result, we are unable to identify which SoundWire links need to be resumed and don't properly handle jack detection.
This patch only clears the WAKESTS bits for the HDaudio codecs detected earlier.
Note that we still clear all WAKESTS bits unconditionally in hda_dsp_ctrl_stop_chip(). The existing behavior is potentially racy if e.g. a jack event happens during a suspend routine, but there's a risk of breaking shutdown or reboot sequences so the code is left as is for now.
