ASoC: omap-hdmi-audio: Set buffer bytes step constraint to 128
Set buffer bytes step constraint to 128. A matching constraint has already been set to period size. This helps PCM setup to tolerate ALSA clients that set the PCM hw params in unusual order. Signed-off-by: Jyri Sarha <jsarha@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
