pinctrl: airoha: Fix return value in pinconf callbacks

[ Upstream commit 563fcd6475931c5c8c652a4dd548256314cc87ed ]

Pinctrl stack requires ENOTSUPP error code if the parameter is not
supported by the pinctrl driver. Fix the returned error code in pinconf
callbacks if the operation is not supported.
