Looks like the function has never been used since it was added by commit b0d94acd634a ("ASoC: Intel: mrfld - add shim save restore"). Removing it fixes the following warning when building with clang:
sound/soc/intel/atom/sst/sst.c:360:20: error: unused function 'sst_restore_shim64' [-Werror,-Wunused-function]
