Merge series "ASoC: core: Two step component registration" from Cezary Rojewski <cezary.rojewski@intel.com>:
Provide a mechanism for true two-step component registration. This mimics device registration flow where initialization is the first step while addition goes as second in line. Drivers may choose to modify component's fields before registering component to ASoC subsystem via snd_soc_add_component. Patchset achieves status quo - behavior of snd_soc_register_component remains unchanged.
