ASoC: SOF: ipc4-topology: Advertise passthrough capable PCMs (using ChainDMA)



If a PCM is set to use ChainDMA then add it to the card->components string
after a marker of iec61937-pcm:, for example on current HDA platforms where
HDMI is set to use ChainDMA:
iec61937-pcm:5,4,3 (the order of the PCM ids can differ)

UCM is expected to parse and use this property to allow applications to
use bytestream passthrough in a standard way.
