This patches consolidates the two implementations at the component level. Unfortunately there are still a couple of CODEC specific debugfs files that are related to legacy ASoC IO that need to be registered. For this a new callback is added to the component struct that will be initialized when a CODEC is registered and will be used to register the CODEC specific files. Once there are no drivers left using legacy IO this can be removed again.

This patch consolidates it at the component level. The resulting code is slightly larger due to all the boiler plate code setting up the indirection for the table based control and DAPM registration. Once all drivers have been update to no longer use the snd_soc_codec_driver and snd_soc_platform_driver specific fields for this the indirection can be removed again. This patch contains two noteworthy hacks that are only meant to be temporary to be able to update drivers and the core in separate incremental patches. The first hack is related to that some DPCM platforms expect that the DAPM widgets for the DAIs of a snd_soc_component are created in the DAPM context of the snd_soc_platform that has the same parent device. For handling this the steal_sibling_dai_widgets attribute is introduced. It gets set for snd_soc_platforms that register DAPM elements. When creating the DAI widgets for a component this flag is checked and if it is found on one of the siblings the component will not create any DAI widgets in its own DAPM context. If the attribute is set on a platform it will look for siblings components and create DAI widgets for them in its own context. The fix for this will be to update the offending drivers to only register a single component rather than two. The second hack deals with the fact that the ASoC card suspend and resume code still needs a list of CODECs that have been registered for the card. To handle this the generic probe and remove path have a check to see if the component is CODEC and if yes add/remove it to the card's CODEC list. While it is possible to clean up the suspend/resume code to not need the CODEC list anymore this is a bit of a chicken and egg problem since it will become easier to clean up the suspend/resume code once there is a unified component layer.

With componentization going forward rtd->codec might be NULL in some cases. This patch prepares the core for this by not registering CODEC specific sysfs files if rtd->codec is NULL. sysfs file removal does not need to be conditionalized as it handles the removal of non-existing files just fine.

They also call the component drivers probe and remove callbacks. This patch makes these things available for generic snd_soc_component drivers rather than only having them for snd_soc_codec and snd_soc_platform drivers.

There are two main differences in the current implementation of the CPU and CODEC DAI lookup: 1) CPU DAIs can be looked up by the DAI name alone and do not necessarily require a component name/of_node. 2) The CODEC DAI search only considers DAIs from CODEC components. For 1) the new helper function will allow to lookup DAIs without providing a component name or of_node, but since snd_soc_register_card() already rejects CODEC DAI link components without neither a of_node or a name we'll never get into the situation where we try to lookup a CODEC DAI without a name/of_node. For 2) the new helper function just always considers all components. Componentization is now at a point where it is possible to register a CODEC as a snd_soc_component rather than a snd_soc_codec, by considering DAIs from all components it is possible to use such a CODEC in a DAI link.

This requires us to have a hack in the ASoC core which does so. Moving the DAPM elements over to the component allows us to remove this hack. While we are at it also move the controls over to the component. The controls don't need the platform for anything other than snd_soc_platform_get_drvdata(), this can easily be replaced by snd_soc_component_get_drvdata(). As the long term goal is to register only a single component this is a step in the right direction.
