iio: adc: dln2-adc: fix build error 

The dln2-adc driver uses interface(s) that are controlled by the
IIO_TRIGGERED_BUFFER Kconfig symbol, so the driver needs to select
that symbol to prevent the build error.

drivers/iio/adc/dln2-adc.o: In function `dln2_adc_probe':
dln2-adc.c:(.text+0x528): undefined reference to `devm_iio_triggered_buffer_setup'
