[PATCH v2 0/6] Use helper function for_each_child_of_node_scoped()

[Ai Chao]

This patch series introduces wrapper functions for_each_child_of_node_scoped().

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.

Summary:

 - Patch 1 ASoC: ppc: Use helper function for_each_child_of_node_scoped()

 - Patch 2 ASoC: aoa: Use helper function for_each_child_of_node_scoped()

 - Patch 3 ASoC: renesas: Use helper function for_each_child_of_node_scoped()

 - Patch 4 ASoC: meson: Use helper function for_each_child_of_node_scoped()

 - Patch 5 ASoC: imx-card: Use helper function for_each_child_of_node_scoped()

 - Patch 6 ASoC: qcom: Use helper function for_each_child_of_node_scoped()
