[PATCH] ASoC: mediatek: common: Switch to for_each_available_child_of_node_scoped()

Using for_each_available_child_of_node_scoped() allows us to get rid of
of_node_put() calls from early returns or breaks in the loop. It also
fixes issues with missing of_node_put() calls.

Switch to for_each_available_child_of_node_scoped() in parse_dai_link_info().
Also drop the braces around if blocks now that the inner block is just
one statement.
