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>;
-       };
