 Required properties for gpio sub nodes:
-  - compatible: "rockchip,gpio-bank"
-  - reg: register of the gpio bank (different than the iomux registerset)
-  - interrupts: base interrupt of the gpio bank in the interrupt controller
-  - clocks: clock that drives this bank
-  - gpio-controller: identifies the node as a gpio controller and pin bank.
-  - #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO

-    GPIO binding documentation for description of particular cells.
-  - interrupt-controller: identifies the controller node as interrupt-parent.
