dt-bindings: gpio: fsl,qoriq-gpio: Add missing mpc8xxx compatibles

The fsl,mpc8349-gpio, fsl,mpc8572-gpio, and fsl,mpc8610-gpio compatibles
are already documented in fsl,qoriq-gpio.yaml. Add the additional
compatibles that use fsl,mpc8349-gpio as a fallback. With that,
the 8xxx_gpio.txt binding document is redundant and can be removed.

-GPIO controllers on MPC8xxx SoCs
-
-This is for the non-QE/CPM/GUTs GPIO controllers as found on
-8349, 8572, 8610 and compatible.
-
-Every GPIO controller node must have #gpio-cells property defined,
-this information will be used to translate gpio-specifiers.
-See bindings/gpio/gpio.txt for details of how to specify GPIO
-information for devices.
-
-The GPIO module usually is connected to the SoC's internal interrupt
-controller, see bindings/interrupt-controller/interrupts.txt (the
-interrupt client nodes section) for details how to specify this GPIO
-module's interrupt.
-
-The GPIO module may serve as another interrupt controller (cascaded to
-the SoC's internal interrupt controller).  See the interrupt controller
-nodes section in bindings/interrupt-controller/interrupts.txt for
-details.
-
-Required properties:
-- compatible:		"fsl,<chip>-gpio" followed by "fsl,mpc8349-gpio"
-			for 83xx, "fsl,mpc8572-gpio" for 85xx, or
-			"fsl,mpc8610-gpio" for 86xx.
-- #gpio-cells:		Should be two. The first cell is the pin number
-			and the second cell is used to specify optional
-			parameters (currently unused).
-- interrupts:		Interrupt mapping for GPIO IRQ.
-- gpio-controller:	Marks the port as GPIO controller.
-
-Optional properties:
-- interrupt-controller:	Empty boolean property which marks the GPIO
-			module as an IRQ controller.
-- #interrupt-cells:	Should be two.  Defines the number of integer
-			cells required to specify an interrupt within
-			this interrupt controller.  The first cell
-			defines the pin number, the second cell
-			defines additional flags (trigger type,
-			trigger polarity).  Note that the available
-			set of trigger conditions supported by the
-			GPIO module depends on the actual SoC.
-
-Example of gpio-controller nodes for a MPC8347 SoC:
-
-	gpio1: gpio-controller@c00 {
-		#gpio-cells = <2>;
-		compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
-		reg = <0xc00 0x100>;
-		interrupt-parent = <&ipic>;
-		interrupts = <74 0x8>;
-		gpio-controller;
-		interrupt-controller;
-		#interrupt-cells = <2>;
-	};
-
-	gpio2: gpio-controller@d00 {
-		#gpio-cells = <2>;
-		compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
-		reg = <0xd00 0x100>;
-		interrupt-parent = <&ipic>;
-		interrupts = <75 0x8>;
-		gpio-controller;
-	};
-
-Example of a peripheral using the GPIO module as an IRQ controller:
-
-	funkyfpga@0 {
-		compatible = "funky-fpga";
-		...
-		interrupt-parent = <&gpio1>;
-		interrupts = <4 3>;
-	};
