pinctrl: starfive: jh7100: ignore disabled device tree nodes
commit 5c584f175d32f9cc66c909f851cd905da58b39ea upstream.
The driver always registers pin configurations in device tree. This can
cause some inconvenience to users, as pin configurations in the base
device tree cannot be disabled in the device tree overlay, even when the
relevant devices are not used.
Ignore disabled pin configuration nodes in device tree.
Fixes: ec648f6b7686 ("pinctrl: starfive: Add pinctrl driver for StarFive SoCs")
