Subject: [PATCH v3 11/11] ASoC: jz4740-i2s: Refactor DAI probe/remove ops as component ops

Move most of the DAI probe/remove logic into component ops.
This makes things more consistent because the AIC clock is
now managed solely from the component side. And it makes it
easier to add codec switching support later on.
