Convert fsl,qoriq-mc to YAML in order to automate the verification
process of dts files. In addition, update MAINTAINERS accordingly
and, while at it, add some missing files.

Changes in v4:
 - use $ref to point to fsl,qoriq-mc-dpmac binding

Changes in v3:
 - dropped duplicated "fsl,qoriq-mc-dpmac" schema and replaced with
   reference to it
 - fixed a dt_binding_check warning

Changes in v2:
 - fixed errors reported by yamllint
 - dropped multiple unnecessary quotes
 - used schema instead of text in description
 - added constraints on dpmac reg property

As there's a dependency on fsl,qoriq-mc-dpmac, this needs to go via 
netdev tree.

-* Freescale Management Complex
-
-The Freescale Management Complex (fsl-mc) is a hardware resource
-manager that manages specialized hardware objects used in
-network-oriented packet processing applications. After the fsl-mc
-block is enabled, pools of hardware resources are available, such as
-queues, buffer pools, I/O interfaces. These resources are building
-blocks that can be used to create functional hardware objects/devices
-such as network interfaces, crypto accelerator instances, L2 switches,
-etc.
-
-For an overview of the DPAA2 architecture and fsl-mc bus see:
-Documentation/networking/device_drivers/ethernet/freescale/dpaa2/overview.rst
-
-As described in the above overview, all DPAA2 objects in a DPRC share the
-same hardware "isolation context" and a 10-bit value called an ICID
-(isolation context id) is expressed by the hardware to identify
-the requester.
-
-The generic 'iommus' property is insufficient to describe the relationship
-between ICIDs and IOMMUs, so an iommu-map property is used to define
-the set of possible ICIDs under a root DPRC and how they map to
-an IOMMU.
-
-For generic IOMMU bindings, see
-Documentation/devicetree/bindings/iommu/iommu.txt.
-
-For arm-smmu binding, see:
-Documentation/devicetree/bindings/iommu/arm,smmu.yaml.
-
-The MSI writes are accompanied by sideband data which is derived from the ICID.
-The msi-map property is used to associate the devices with both the ITS
-controller and the sideband data which accompanies the writes.
-
-For generic MSI bindings, see
-Documentation/devicetree/bindings/interrupt-controller/msi.txt.
-
-For GICv3 and GIC ITS bindings, see:
-Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml.
-
-Required properties:
-
-    - compatible
-        Value type: <string>
-        Definition: Must be "fsl,qoriq-mc".  A Freescale Management Complex
-                    compatible with this binding must have Block Revision
-                    Registers BRR1 and BRR2 at offset 0x0BF8 and 0x0BFC in
-                    the MC control register region.
-
-    - reg
-        Value type: <prop-encoded-array>
-        Definition: A standard property.  Specifies one or two regions
-                    defining the MC's registers:
-
-                       -the first region is the command portal for the
-                        this machine and must always be present
-
-                       -the second region is the MC control registers. This
-                        region may not be present in some scenarios, such
-                        as in the device tree presented to a virtual machine.
-
-    - ranges
-        Value type: <prop-encoded-array>
-        Definition: A standard property.  Defines the mapping between the child
-                    MC address space and the parent system address space.
-
-                    The MC address space is defined by 3 components:
-                       <region type> <offset hi> <offset lo>
-
-                    Valid values for region type are

-        Value type: <u32>
-        Definition: Must be 1.
-
-Sub-nodes:
-
-        The fsl-mc node may optionally have dpmac sub-nodes that describe
-        the relationship between the Ethernet MACs which belong to the MC
-        and the Ethernet PHYs on the system board.
-
-        The dpmac nodes must be under a node named "dpmacs" which contains
-        the following properties:
-
-            - #address-cells
-              Value type: <u32>
-              Definition: Must be present if dpmac sub-nodes are defined and must
-                          have a value of 1.
-
-            - #size-cells
-              Value type: <u32>
-              Definition: Must be present if dpmac sub-nodes are defined and must
-                          have a value of 0.
-
-        These nodes must have the following properties:
-
-            - compatible
-              Value type: <string>
-              Definition: Must be "fsl,qoriq-mc-dpmac".
-
-            - reg
-              Value type: <prop-encoded-array>
-              Definition: Specifies the id of the dpmac.
-
-            - phy-handle
-              Value type: <phandle>
-              Definition: Specifies the phandle to the PHY device node associated
-                          with the this dpmac.
-Optional properties:
-
-- iommu-map: Maps an ICID to an IOMMU and associated iommu-specifier
-  data.
-
-  The property is an arbitrary number of tuples of
-  (icid-base,iommu,iommu-base,length).
-
-  Any ICID i in the interval [icid-base, icid-base + length) is
-  associated with the listed IOMMU, with the iommu-specifier
-  (i - icid-base + iommu-base).
-
-- msi-map: Maps an ICID to a GIC ITS and associated msi-specifier
-  data.
-
-  The property is an arbitrary number of tuples of
-  (icid-base,gic-its,msi-base,length).
-
-  Any ICID in the interval [icid-base, icid-base + length) is
-  associated with the listed GIC ITS, with the msi-specifier
-  (i - icid-base + msi-base).
-
-Deprecated properties:
-
-    - msi-parent
-        Value type: <phandle>
-        Definition: Describes the MSI controller node handling message
-                    interrupts for the MC. When there is no translation
-                    between the ICID and deviceID this property can be used
-                    to describe the MSI controller used by the devices on the
-                    mc-bus.
-                    The use of this property for mc-bus is deprecated. Please
-                    use msi-map.
