Jonathan Hunter eabaeedaa6 ASoC: tegra-alt: Set device data before initialising RPM ...

The device data for a given driver must be set before enabling
runtime-pm otherwise this could results in a crash if the runtime-pm
callback is called before the device data is set where it is expected
that the device data has been initialised.

Furthermore, most drivers will directly call the runtime-pm callback
to power-up the device if runtime-pm is not enabled in the kernel
config and so many drivers would crash if runtime-pm is not enabled.

Fix this by setting the device data early in the driver probe.
