iio: srf08: fix link error "devm_iio_triggered_buffer_setup" undefined

Browse Source 
commit 511051d509ec54642dd6d30fdf2caa33c23619cc upstream.

Functions for triggered buffer support are needed by this module.
If they are not defined accidentally by another driver, there's an error
thrown out while linking.

Add a select of IIO_BUFFER and IIO_TRIGGERED_BUFFER in the Kconfig file.
