Irda: Add Irda System Service for I9505

Add Irda System Service that is compatible with the Galaxy S4.
This is not a perfect solution yet, but it does work and should therefore be a starting point.
I do not know how to make this code exclusive to the S4, maybe someone can help me out with that.

PatchSet 2: Now the Irda service is not started by default. It can be enabled via overlay.

PatchSet 3: Rebase
