[PATCH 5/6] ASoC: imx-card: Use helper function for_each_child_of_node_scoped()

[Ai Chao]

The for_each_child_of_node_scoped() helper provides a scope-based
clean-up functionality to put the device_node automatically, and
as such, there is no need to call of_node_put() directly.

Thus, use this helper to simplify the code.
