dt-bindings: fsl: convert fsl,layerscape-scfg to YAML 



Convert the fsl,layerscape-scfg binding to the new YAML format.

In the device trees, the device node always have a "syscon"
compatible, which wasn't mentioned in the previous binding.

Also added, compared to the original binding, is the
interrupt-controller subnode as used in arch/arm/boot/dts/ls1021a.dtsi
as well as the litte-endian and big-endian properties.

Freescale SCFG



SCFG is the supplemental configuration unit, that provides SoC specific

configuration and status registers for the chip. Such as getting PEX port

status.



Required properties:

  - compatible: Should contain a chip-specific compatible string,

	Chip-specific strings are of the form "fsl,<chip>-scfg",

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

	ls1012a, ls1021a, ls1043a, ls1046a, ls2080a.



  - reg: should contain base address and length of SCFG memory-mapped registers



Example:

	scfg: scfg@1570000 {

		compatible = "fsl,ls1021a-scfg";

		reg = <0x0 0x1570000 0x0 0x10000>;

	};
