With S20_3LE format case, the sysclk = rate * 384, the bclk = rate * 20 * 2, there is no proper bclk divider for 384 / 40, because current condition needs exact match. So driver fails to configure the clocking:
wm8962 3-001a: Unsupported BCLK ratio 9
Fix this by relaxing bitclk divider searching, so that when no exact value can be derived from sysclk pick the closest value greater than expected bitclk.
