Commit 08e05d1fce5c ("ti-adc081c: Initial triggered buffer support") added
triggered buffer support but that also requires CONFIG_IIO_TRIGGERED_BUFFER,
otherwise we get errors from linker such as:
drivers/built-in.o: In function `adc081c_remove':
drivers/iio/adc/ti-adc081c.c:225: undefined reference to `iio_triggered_buffer_cleanup'
Fix these by explicitly selecting both CONFIG_IIO_TRIGGERED_BUFFER and
CONFIG_IIO_BUFFER in Kconfig for the driver.

If you say yes here you get support for Texas Instruments ADC081C,
ADC101C and ADC121C ADC chips.
