ASoC: simple-card: Add pm callbacks to platform driver
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.

Reverting it fixes the problem for me.

when I'm talking to journalists I just say "programmer" or something like that.
