pinctrl: samsung: update child reference drop comment

Commit 954445c ("pinctrl: samsung: Drop redundant node parameter in
samsung_banks_of_node_get()") modified the name of the function used to
release child nodes from samsung_drop_banks_of_node() to
samsung_banks_node_put(). Update the comment to use the current function
name.
