ASoC: rsnd: fix DALIGN register for SSIU
commit ef8e14794308a428b194f8b06ad9ae06b43466e4 upstream. The current driver only sets 0x76543210 and 0x67452301 for DALIGN. This doesn’t work well for TDM split and ex-split mode for all SSIU. This patch programs the DALIGN registers based on the SSIU number.
