ASoC: simple card: set cpu-dai sysclk with mclk-fs
Allows to request a specific mclk frequency per cpu_dai. To support some codecs with mclk provided by the cpu_dai, the mclk rate must be set depending on frame rate. Signed-off-by: Arnaud Pouliquen <arnaud.pouliquen@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>
