ASoC: codecs: wsa883x: fix unnecessary initialisation

Browse source 
The soundwire update_status() callback may be called multiple times with
the same ATTACHED status but initialisation should only be done when
transitioning from UNATTACHED to ATTACHED.

This avoids repeated initialisation of the codecs during boot of
machines like the Lenovo ThinkPad X13s:
