Subject: [PATCH v2] gpio: rockchip: release reference to device node

Added a call to of_node_put(pctlnp) in rockchip_gpio_probe to properly
release the reference to the device node, improving memory management
and preventing potential leaks.

Fixes: 936ee2675eee ("gpio/rockchip: add driver for rockchip gpio")
