Without the triggered buffer code, we get a link error:
drivers/iio/adc/at91-sama5d2_adc.o: In function `at91_adc_probe':
at91-sama5d2_adc.c:(.text+0x938): undefined reference to `devm_iio_triggered_buffer_setup'
This adds a Kconfig 'select' statement like other ADC
drivers have it already.
Fixes: 5e1a1da0f8c9 ("iio: adc: at91-sama5d2_adc: add hw trigger and buffer support")

Say yes here to build support for Atmel SAMA5D2 ADC which is
available on SAMA5D2 SoC family.

Doh. Shouldn't have missed this one.
Thanks Arnd,
Applied to the togreg branch of iio.git will head for Greg and hence linux-next
in a few days.
