ASoC: rsnd: enable SRC sync even FIN = FOUT

Browse Source 
Current SRC (= Sampling Rate Converter) is supporting
SYNC mode and ASYNC mode. Current src.c cares SRC if FIN != FOUT.
Here, SYNC mode will be used for tweak, so it will be used
even FIN = FOUT. This patch enables SRC sync in such situation
