I think here what I'd expect to see is only one CPU DAI specified for the back end link in the CPU that is actually linked to the CODEC and the front ends being worked out by the drivers, unless there are systems where the set of front ends can be configured at system build time (as opposed to from software at runtime) somehow.
This means BE don't know who is FE. The implementation can be more easy if it has connect-to / connect-from property (I'm not sure this is good naming...)
We don't need to get this from DT if it's fixed in the SoC - the driver for the SoC can know this. The whole front end/back end thing is a bit of a Linuxism.
