Currently the logic that handles hw_params->ce_remap is inline code, both for doing the remap and the unmap. An upcoming change needs to do the unmap in a second place, so refactor the unmap logic into a separate function. And although it is only called from one place, refactor the remap logic as well to have functional symmetry. No functional changes, compile tested only.
