CODECs without any outputs now remain powered down, which means any
paths to these codecs also remain powered down.
Add an always-enabled output pin widget to the spdif transceiver codec.
This enables DAPM to correctly identify that the spdif transceiver is
in use when playback is enabled, which will then allow DAPM to power up
any links from the CPU DAI to the S/PDIF transceiver.

Generally, S/PDIF supports 20bit and optional 24bit samples. Thus add these
two formats for the dummy codec drivers.
If one S/PDIF controller has its own limitation, its CPU DAI driver should
set the supported format by its own circumstance, since the soc-pcm driver
will use the intersection of cpu_dai's formats and codec_dai's formats.

Transceiver usually means receiver + transmitter. This codec can do only
transmit. Update driver accordingly.
