dt-bindings: pinctrl: pinctrl-single: Fix pinctrl-single,gpio-range description

The binding is supposed to describe the properties of each element
of the pinctrl-single,gpio-range array entry, however when we use
"- items:" instead of "items:", it explicitly describes that there
is just a single entry in the array.

The pinctrl-single,gpio-range property should describe more than one
entry in the array. Fix the typo and adjust the alignment of the
description of the entries appropriately.
