pinctrl: cirrus: Fix fwnode leak in cs42l43_pin_probe()

Browse source

[ Upstream commit 9b07cdf86a ]

The driver calls fwnode_get_named_child_node() which takes a reference
on the child node, but never releases it, which causes a reference leak.

Fix by using devm_add_action_or_reset() to automatically release the
reference when the device is removed.
