ASoC: fsl-asoc-card: add sysclk_ratio for calculate sysclk frequency

The sysclk frequency can be calculated from sample rate multiply ratio.
When sysclk_freq is not configured, but sysclk_ratio is configured, then
calculate sysclk frequency according to sysclk_ratio.

Apply this change for wm8524 codec.
