iio: Documentation: update definitions for bufferY and scan_elements
Since the new change to the IIO buffer infrastructure, the buffer/ and scan_elements/ directories have been merged into bufferY/ to have some attributes available per-buffer. This change updates the ABI docs to reflect this change. The hwfifo attributes are not updated, as for now these should be used via the legacy buffer/ directory until they are moved into core.
