Commit Message

Due to lack of maintainance and stall of development for a few years now,
and since no new features will ever be added upstream, remove the
OX810 and OX820 gpio bindings.

-* Oxford Semiconductor OXNAS SoC GPIO Controller
-
-Please refer to gpio.txt for generic information regarding GPIO bindings.
-
-Required properties:
- - compatible: "oxsemi,ox810se-gpio" or "oxsemi,ox820-gpio"
- - reg: Base address and length for the device.
- - interrupts: The port interrupt shared by all pins.
- - gpio-controller: Marks the port as GPIO controller.
- - #gpio-cells: Two. The first cell is the pin number and
-   the second cell is used to specify the gpio polarity as defined in
-   defined in <dt-bindings/gpio/gpio.h>:
-      0 = GPIO_ACTIVE_HIGH
-      1 = GPIO_ACTIVE_LOW
- - interrupt-controller: Marks the device node as an interrupt controller.
- - #interrupt-cells: Two. The first cell is the GPIO number and second cell
-   is used to specify the trigger type as defined in
-   <dt-bindings/interrupt-controller/irq.h>:
-      IRQ_TYPE_EDGE_RISING
-      IRQ_TYPE_EDGE_FALLING
-      IRQ_TYPE_EDGE_BOTH
- - gpio-ranges: Interaction with the PINCTRL subsystem, it also specifies the
-   gpio base and count, should be in the format of numeric-gpio-range as
-   specified in the gpio.txt file.
-
-Example:
-
-gpio0: gpio@0 {
-	compatible = "oxsemi,ox810se-gpio";
-	reg = <0x000000 0x100000>;
-	interrupts = <21>;
-	#gpio-cells = <2>;
-	gpio-controller;
-	interrupt-controller;
-	#interrupt-cells = <2>;
-	gpio-ranges = <&pinctrl 0 0 32>;
-};

-	button-esc {
-		label = "ESC";
-		linux,code = <1>;
-		gpios = <&gpio0 12 0>;
