Subject: [PATCH v2 1/4] ASoC: fsl: imx_pcm_rpmsg: Register component with rpmsg channel name

Machine driver uses rpmsg channel name to link this platform component.
However if the component is re-registerd card will not find this new
created component in snd_soc_try_rebind_card().

Explicitly register this component with rpmsg channel name so that
card can always find this component.
