ASoC: SOF: Intel: hda-ctrl: only clear WAKESTS for HDaudio codecs

Browse Source 
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.
