On SM8450 and SC8280XP, the Q6APM is a bit different:
This is not specific to SM8450 or SC8280XP its part of AudioReach apm which deals with both backends and pcm.
In old Elite architecture we had a dedicated service AFE to deal with Backend dais, now APM does all.

- It is used as a platform DAI link, so it needs #sound-dai-cells.
- It has two DAI children, so add new "bedais" node.
