Subject: [PATCHv4 2/9] ASoC: fsl-asoc-card: add second dai link component for codecs

Add a second dai link component for codecs that will be used for the
generic codec use case.
It will use spdif_receiver and spdif_transmitter drivers as dummy codec
drivers, needing 2 codecs slots for the links.

To prevent deferring in use cases using only one codec, also set
by default the number of codecs to 1 for the relevant dai links.
