Sound cards may allow using different main clock inputs. In the generic
fsl-asoc-card driver, these values are hardcoded for each specific card
configuration.
Let's make it more flexible, allowing setting mclk-id from the
device-tree node. Otherwise, the default value for each card
configuration is used.
