The IS31FL319X series features an SDB shutdown pin.
Driving it low (active low) places the chip into hardware shutdown
mode for power saving, while all register contents are preserved
and registers are not reset.
Add description for the shutdown down (SDB) pin and fix the example
device tree binding.
