Subject: [PATCH] ASoC: rockchip: i2s: Adjust devm usage

Remove use of snd_soc_unregister_component in remove function
as devm_snd_soc_register_component in probe function automatically
handles it.

Also, convert call of snd_dmaengine_pcm_register to managed resource
function devm_snd_dmaengine_pcm_register and remove usage of
snd_dmaengine_pcm_unregister in probe and remove functions.
