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.

Note: This has been tested in the ChromeOS-2.6.37 kernel, with a backport
of ASoC for-2.6.39, on Seaboard. I have not tested it in mainline (I'm not
sure whether mainline has PM support for the Tegra platform yet), although
I did at least compile-test it.
