* QE Firmware Node

This node defines a firmware binary that is embedded in the device tree, for
the purpose of passing the firmware from bootloader to the kernel, or from
the hypervisor to the guest.

The firmware node itself contains the firmware binary contents, a compatible
property, and any firmware-specific properties.  The node should be placed
inside a QE node that needs it.  Doing so eliminates the need for a
fsl,firmware-phandle property.  Other QE nodes that need the same firmware
should define an fsl,firmware-phandle property that points to the firmware node
in the first QE node.

The fsl,firmware property can be specified in the DTS (possibly using incbin)
or can be inserted by the boot loader at boot time.

Required properties:
  - compatible
      Usage: required
      Value type: <string>
      Definition: A standard property.  Specify a string that indicates what
          kind of firmware it is.  For QE, this should be "fsl,qe-firmware".

   - fsl,firmware
      Usage: required
      Value type: <prop-encoded-array>, encoded as an array of bytes
      Definition: A standard property.  This property contains the firmware
          binary "blob".

Example:
	qe1@e0080000 {
		compatible = "fsl,qe";
		qe_firmware:qe-firmware {
			compatible = "fsl,qe-firmware";
			fsl,firmware = [0x70 0xcd 0x00 0x00 0x01 0x46 0x45 ...];
		};
		...
	};

	qe2@e0090000 {
		compatible = "fsl,qe";
		fsl,firmware-phandle = <&qe_firmware>;
		...
	};
