iio: adc: ad_sigma_delta: remove ad_sd_{setup,cleanup}_buffer_and_trigger()

Since all AD Sigma-Delta drivers now use the
devm_ad_sd_setup_buffer_and_trigger() function, we can remove the old
ad_sd_{setup,cleanup}_buffer_and_trigger() functions.

This way we can discourage new drivers that use the ad_sigma_delta
lib-driver to use these (older functions).
