ASoC: Let snd_soc_platform subclass snd_soc_component
There is an increasing amount of code that is very similar between platforms, CODECS and other components. Making platforms a component will allow us to share this code. For now the patch just adds component and component_driver fields to the platform and platform_driver structs and registers the platform as a component. Followup patches will be used to consolidate code between the different types of components. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>
