[PATCH] l1: add CBCH flag to dedicated mode

I would make it a generic 'flags' bit fields with a DM_FLAG_CBCH or
something like that.
This way we can re-use this for other special modes (I'm thinking like
a sniff more or no tx or role swap modes).

I don't like the idea of abusing audio_mode, but I'll look into the
code tomorrow see if it worth combining more stuff into a parameters.
