[PATCH 2/2] iio: adc: stm32-dfsdm: fix triggered buffer build dependency

[Fabrice Gasnier]

This fixes build errors seen when CONFIG_STM32_DFSDM_ADC is set, as
stm32-dfsdm-adc driver now also relies on triggered buffer API:

Fixes: 11646e81d775 ("iio: adc: stm32-dfsdm: add support for buffer modes")
