[PATCH v2] ASoC: Tegra: Suspend/resume support

[PATCH v2] ASoC: Tegra: Suspend/resume support

[Stephen Warren]

ASoC machine drivers that are their own platform_driver (as opposed to
those using the soc-audio platform_driver) need to explicitly set up
power-management operation callbacks.

To avoid cut/paste, snd_soc_pm_ops also needs to be exported.

v2: Export and use snd_soc_pm_ops directly instead of lazily cut and
    pasting it.

Applied, thanks.
