ASoC: imx-pcm-rpmsg: Register different platform drivers

Browse Source 
This patch can register different ASoC platform drivers if there are
several rpmsg channels. Thus sound cards based on different rpmsg
channels can link to their respective platform drivers. Besides, the
name of driver is equal to the name of rpmsg channel.
