pinctrl: starfive: jh7110: ignore disabled device tree nodes
commit f6e3b40a2c89c1d832ed9cb031dc9825bbf43b7c 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.
