ASoC: rsnd: SSI PIO adjust to 24bit mode
commit 90431eb49bff ("ASoC: rsnd: don't use PDTA bit for 24bit on SSI") fixups 24bit mode data alignment, but PIO was not cared. This patch fixes PIO mode 24bit data alignment Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
