Building the Rockchip saradc driver can trigger the following error if the
driver is compiled into the kernel, but the IIO triggered buffer is not:
aarch64-linux-gnu-ld: drivers/iio/adc/rockchip_saradc.o: in function `rockchip_saradc_probe':
/path/to/linux/drivers/iio/adc/rockchip_saradc.c:427: undefined reference to `devm_iio_triggered_buffer_setup'
This is because commit 4e130dc7b413 ("iio: adc: rockchip_saradc: Add
support iio buffers") added support for industrial I/O triggered buffers,
but didn't update Kconfig to build the required file. Fix that.
Fixes: 4e130dc7b413 ("iio: adc: rockchip_saradc: Add support iio buffers")

Say yes here to build support for the SARADC found in SoCs from
Rockchip.
