iio:adc: at91 requires the input subsystem
Building the at91 adc driver with CONFIG_INPUT disabled results in this build error: ERROR: "input_event" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_unregister_device" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_free_device" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_register_device" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_set_abs_params" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_allocate_device" [drivers/iio/adc/at91_adc.ko] undefined! To make sure we can build random configurations, this adds a Kconfig dependency on CONFIG_INPUT, as we do for other similar drivers.
