ASoC: Tegra TrimSlice machine: Use devm_ APIs and module_platform_driver
module_platform_driver saves some boiler-plate code. The devm_ APIs remove the need to manually clean up allocations, thus removing some code. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
