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

Browse Source 
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>;
};
