Revert "[media] rc: rc-loopback: Add loopback of filter scancodes"

This reverts commit 2e4ebde269236da2a41183522127715b6d9d80ce.

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.
