ASoC: soc-core: move soc_probe_component() position
It is easy to read code if it is cleanly using paired function/naming, like start <-> stop, register <-> unregister, etc, etc. But, current ALSA SoC code is very random, unbalance, not paired, etc. It is easy to create bug at the such code, and it will be difficult to debug. soc_probe_comonent() has paired soc_remove_comonent(), but, these are implemented at different place. So it is difficult to confirm code. This patch moves soc_probe_component() next to soc_remove_component().
