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.

Signed-off-by: Stephen Warren swarren@nvidia.com --- v2: Export and use snd_soc_pm_ops directly instead of lazily cut and pasting it.
