[PATCH] pinctrl: equilibrium: Fix device node reference leak in pinbank_init()

[Felix Gu <ustc.gu@gmail.com>]

When calling of_parse_phandle_with_fixed_args(), the caller is
responsible to call of_node_put() to release the reference of device
node.

In pinbank_init(), the reference of the node obtained from the
"gpio-ranges" property is never released, resulting in a reference
count leak.

Add the missing of_node_put() call to fix the leak.
