dt-bindings: gpio: cavium,thunder-8890: Remove DT binding 



Remove the cavium,thunder-8890 GPIO binding as there are no active
use cases. The binding is unused as the corresponding kernel driver
binds via PCI and not the compatible.

Cavium ThunderX/OCTEON-TX GPIO controller bindings



Required Properties:

- reg: The controller bus address.

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

- #gpio-cells: Must be 2.

  - First cell is the GPIO pin number relative to the controller.

  - Second cell is a standard generic flag bitfield as described in gpio.txt.



Optional Properties:

- compatible: "cavium,thunder-8890-gpio", unused as PCI driver binding is used.

- interrupt-controller: Marks the device node as an interrupt controller.

- #interrupt-cells: Must be present and have value of 2 if

                    "interrupt-controller" is present.

  - First cell is the GPIO pin number relative to the controller.

  - Second cell is triggering flags as defined in interrupts.txt.



Example:



gpio_6_0: gpio@6,0 {

	compatible = "cavium,thunder-8890-gpio";

	reg = <0x3000 0 0 0 0>; /*  DEVFN = 0x30 (6:0) */

	gpio-controller;

	#gpio-cells = <2>;

	interrupt-controller;

	#interrupt-cells = <2>;

};
