ASoC: mt6359: Fix refcount leak bug

[ Upstream commit f0b3eaa17aa73307f759d353211a27e497ebcc55 ]

In mt6359_parse_dt() and mt6359_accdet_parse_dt(), we should call
of_node_put() for the reference returned by of_get_child_by_name()
which has increased the refcount.

Fixes: e50f23f44fc1 ("ASoC: mt6359: fix failed to parse DT properties")
Fixes: ad52183e6765 ("ASoC: mediatek: mt6359: add MT6359 accdet jack driver")
