4.19-stable review patch. If anyone has any objections, please let me know.

From: Tom Zanussi tom.zanussi@linux.intel.com
commit 912201345f7c39e6b0ac283207be2b6641fa47b9 upstream.
All var_refs are now handled uniformly and there's no reason to treat the synth_refs in a special way now, so remove them and associated functions.
