ASoC: SOF: Intel: hda-codec: preserve WAKEEN values

Browse Source 
Since LunarLake, we use the HDadio WAKEEN/WAKESTS to detect wakes for
SoundWire codecs. Unfortunately, the existing code in
hda_codec_jack_wake_enable() unconditionally resets the WAKEEN bits.

This patch changes the initialization to preserve SoundWire WAKEEN
bits. For HDAudio codecs the same strategy is used, WAKEEN is only set
when the jacktbl.used property is set.
