Subject: [PATCH v5 1/5] dt-bindings: pinctrl: modify gpio-cells property

From: Xianwei Zhao <xianwei.zhao@...ogic.com>

Extend the value range of #gpio-cells property, including [2, 3],
to compatible with Amlogic A4 SoC and later chips's pinctrl module.
The early GPIO parameter number is 2, and the later GPIO parameter
number is 3.
