Irda: Add Irda System Service

This is not a perfect solution yet, but it does work and should therefore be a starting point.
It needs work to be functional on devices other than the Galaxy S4

* The Irda service is not started by default. It can be enabled via overlay.
* Uses a HAL module to communicate with sysfs
