ASoC: da7213: Add a set_bclk_ratio method
Following [1], it becomes harder for the CPU DAI to know the correct BCLK ratio. We can either bake the same knowledge into the sound card driver, or implement and use set_bclk_ratio on the codec. This commit does the latter. [1] commit c89e652e ("ASoC: da7213: Add support for mono, set frame width to 32 when possible") Signed-off-by: Phil Elwell <phil@raspberrypi.com>
