[media] tm6000: rework and fix IR
Hi
This patch didn't kill Stefan's remotes and just for upload my good part of code.
1. Add some code for show IR activity
2. Add filter for IR remotes
3. Split remotes to different types.
4. Fix stop interrupt pipe when isoc pipe started.
When we decide general way of IR I'll add support our remotes.
For our customers I'll made custom temporary patch without this part.
