ramips: adjusted pinctrl-aw9523 for kernel 6.6

Compatiblity with kernel 6.6 for Awinic AW9523B i2c pin controller driver.
It follows the kernel patch: i2c: Drop legacy callback .probe_new() (https://github.com/torvalds/linux/commit/5eb1e6e459cfa025f79c43014f66ff62a55542f1)
and kernel patch: gpiolib: Get rid of not used of_node member (https://github.com/torvalds/linux/commit/70d0fc4288dabd65025fde7774b4f9262afa9034)
