dt-bindings: gpio: mpc8xxx: Convert to yaml format 



Convert binding doc from txt to yaml.

Remove redundated "gpio1: gpio@2300000" example.
Add gpio-controller at example "gpio@1100".

* Freescale MPC512x/MPC8xxx/QorIQ/Layerscape GPIO controller



Required properties:

- compatible : Should be "fsl,<soc>-gpio"

  The following <soc>s are known to be supported:

	mpc5121, mpc5125, mpc8349, mpc8572, mpc8610, pq3, qoriq,

	ls1021a, ls1043a, ls2080a, ls1028a, ls1088a.

- reg : Address and length of the register set for the device

- interrupts : Should be the port interrupt shared by all 32 pins.

- #gpio-cells : Should be two.  The first cell is the pin number and

  the second cell is used to specify the gpio polarity:

      0 = active high

      1 = active low



Optional properties:

- little-endian : GPIO registers are used as little endian. If not

                  present registers are used as big endian by default.



Example of gpio-controller node for a mpc5125 SoC:



gpio0: gpio@1100 {

	compatible = "fsl,mpc5125-gpio";

	#gpio-cells = <2>;

	reg = <0x1100 0x080>;

	interrupts = <78 0x8>;

};



Example of gpio-controller node for a ls2080a SoC:



gpio0: gpio@2300000 {

	compatible = "fsl,ls2080a-gpio", "fsl,qoriq-gpio";

	reg = <0x0 0x2300000 0x0 0x10000>;

	interrupts = <0 36 0x4>; /* Level high type */

	gpio-controller;

	little-endian;

	#gpio-cells = <2>;

	interrupt-controller;

	#interrupt-cells = <2>;

};





Example of gpio-controller node for a ls1028a/ls1088a SoC:



gpio1: gpio@2300000 {

	compatible = "fsl,ls1028a-gpio", "fsl,ls1088a-gpio", "fsl,qoriq-gpio";

	reg = <0x0 0x2300000 0x0 0x10000>;

	interrupts = <GIC_SPI 36 IRQ_TYPE_LEVEL_HIGH>;

	gpio-controller;

	#gpio-cells = <2>;

	interrupt-controller;

	#interrupt-cells = <2>;

	little-endian;
