ZTE ZX296702 GPIO controller

Required properties:

- compatible : "zte,zx296702-gpio"

- #gpio-cells : Should be two. The first cell is the pin number and the

second cell is used to specify optional parameters:

- bit 0 specifies polarity (0 for normal, 1 for inverted)

- gpio-controller : Marks the device node as a GPIO controller.

- interrupts : Interrupt mapping for GPIO IRQ.

- gpio-ranges : Interaction with the PINCTRL subsystem.
