Back camera slider detection switch

The back camera and flash LED have a cover slider, which position is detected with a slider switch (slider sensor).
When the slider covers the back camera and flash LED (upper position), the slider switch is open circuit (not
pressed) and the OMAP1710 is connected to VIO. When the slider is slid down, the switch is pressed and it
connects the Helen pin mcbsp1_sync to GND (typical 160mV) and activates the back camera application
