ASoC: wsa881x: Avoid query temp during suspend

Runtime suspend in slimbus driver makes QMI call which takes
wakelock and result in first system suspend to fail. As a result
of first suspend fail, POST_PM_SUSPEND event is dispatched to
thermal core which registered to pm notifier. WSA being one
of registered thermal zone gets query for temperature, and makes
slimbus reads/writes which will result in runtime resume of
slimbus driver to happen. System suspend fails again continuously
in this endless loop as slimbus runtime suspend will make QMI call
again.
Update wsa temp sensor to handle suspend event by registering to
pm notifier and ignore the temperature request from thermal core
at resume or during Hibernation restore. This will avoid
slimbus reads/writes during suspend in progress and
allow XO shutdown to happen.
