Subject: ASoC: rsnd: ssi: 24bit data needs right-aligned settings
From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>
commit f46a93b820eb3707faf238cd769a004e2504515f upstream.
Data left/right aligned is controlled by PDTA bit on SSICR.
But default is left-aligned. Thus 24bit sound will be very small sound
without this patch.
