iio: adc: select triggered buffer for sama5d2 adc
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")
