Add Add snd_soc_component_{get,set}_drvdata() similar to snd_soc_codec_{get,set}_drvdata() and snd_soc_platform_{get,set}_drvdata(). Also update them to use the new functions internally.

Resource allocations should happen in driver probe callback rather than in snd_soc_platform probe functions. Especially if the resource is device managed. The snd_soc_* probe/remove functions are mainly intended to be used for things that require the component to be already bound to a card.

There are no users left and new users should rather use the component_driver struct embedded in the snd_soc_platform_driver struct to do this. E.g.:

static const struct snd_soc_platform_driver foobar_driver = { .component_driver = { .dapm_widgets = ..., .num_dapm_widgets = ..., ..., }, ... };

instead of

static const struct snd_soc_platform_driver foobar_driver = { .dapm_widgets = ..., .num_dapm_widgets = ..., ... };

This also allows us to remove the steal_sibling_dai_widgets hack.
