soc-core core already has soc_find_component() which find component from device node. Let's use existing function to find component.

Hi,
This patch causes crash on today's linux-next apparently because "CPU DAI" is not registered now, any ideas?
FWIW I am seeing the same crash/regression, however, the bisect is pointing to commit b9f2e25c599bbbf0646957e07ebb72b942c286cc ("ASoC: soc-core: use soc_find_component() at snd_soc_find_dai()") and reverting this commit fixes the problem for me.
Dmitry, are you sure it is this commit? They do have a similar name.
Cheers Jon
