Add 'maxim,override-mode' property to allow the user to toggle the pin configured chip operation mode and 'maxim,fsync-config' to configure the chip for relaying a frame synchronization signal, received from deserializer, to the attached sensor. The latter is needed for synchronizing the images in multi-sensor setups.
