Sean Young e5499dd725 media: lirc: revert removal of unused feature flags
Commit b2a90f4fcb ("media: lirc: remove unused lirc features") removed
feature flags which were never implemented, but they are still used by
the lirc daemon went built from source.

Reinstate these symbols in order not to break the lirc build.
