[PATCH] ASoC: simple-card: Add pm callbacks to platform driver

[PATCH] ASoC: simple-card: Add pm callbacks to platform driver

[Peter Ujfalusi]

Set snd_soc_pm_ops for the pm ops to make sure that the ASoC level of PM
operations are going to happen. This is needed to get suspend/resume
working correctly when the audio is using simple-card.

Hi Mark,

we have moved most of the TI boards to use simple-card and I have noticed that
we have quite bad regression because of it caused by simple-card not having the
pm ops configured. This will render audio to not recover after suspend/resume
when the audio IP is loosing context.

Regards,
Peter
