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.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:
./Documentation/devicetree/bindings/misc/fsl,qoriq-mc.yaml:128:9: [warning] wrong indentation: expected 10 but found 8 (indentation)

dtschema/dtc warnings/errors:


See https://patchwork.ozlabs.org/patch/1395017

The base for the patch is generally the last rc1. Any dependencies
should be noted.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

Don't need quotes.

Don't need quotes. You need '|' for a literal block to keep formatting.

But all this should be expressed as schema...

Thanks a lot for taking a look. Will take care in the next spin.

PS. Nice work on the validation tools. My ~1 month old version didn't
catch those errors.

-* 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.

-
-                    The MC address space is defined by 3 components:

-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

-Optional properties:
-
-- iommu-map: Maps an ICID to an IOMMU and associated iommu-specifier

-
-  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

-                    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
