Bluray Drive, disc presence detector

There are 2 syscon pins dedicated to detect the disc insertion. One of pins powers a IR-LED (emitter), and the other pin is connected to a photo-transistor (receiver), both aligned with each other
When the disc interrupts the light beam a control signal is sent to syscon in the receiver pin. See BL1-001 and BL2-001
