Revert "[media] rc: rc-ir-raw: Add scancode encoder callback"
This reverts commit 9869da5bacc5c9b865a183bd36c04be76cdd325d.
The current code is not mature enough, the API should allow a single
protocol to be specified. Also, the current code contains heuristics
that will depend on module load order.
