For some reason we ended up adding only 4 out of 11 compute cb's for
CDSP, add the missing compute cb. This will also improve the end
user-experience by enabling running multiple AI usecases in parallel.

That doesn't match the patternProperties "(compute-)?cb@[0-9]*$".
Is the reg an index, or an "address"? Should we use base 10, or should
we fix the yaml?
