ASoC: imx-audio-rpmsg: Create rpmsg channel for MICFIL 



Rpmsg channel for MICFIL can also be created through rpmsg name service
announcement. If this driver is probed, Cortex-A can access MICFIL
which is actually controlled by Cortex-M through rpmsg channel for
MICFIL. This driver also helps register ASoC platform device thus use
of PLATFORM_DEVID_AUTO macro in API can automatically create device for
each rpmsg channel.
