No, this is getting silly.  We need to just make DAPM mandatory for all
contexts - they get essentially no testing from people doing active
development and the special casing they require is just a constant
source of fragility.

For CODECs we can easily add some widgets for them based on the DAI, for
cards we should just shove a random widget in there with the name of the
card, it doesn't need to be wired up to anything.
