ASoC: Automatically initialize regmap for all components

So far regmap is only automatically initialized for CODECs. Now that we have the
infrastructure in place to let components have DAPM widgets and controls that
want to use the generic regmap based IO also make sure to automatically
initialize regmap for all components.
