The Arm Ltd board bindings are a bit unusual in that they define child
nodes for various syscon's. The schemas are also incomplete as they lack
constraints on having additional properties and some properties are
missing. As the bindings for the different platforms only vary by
compatibles, combine them into a single schema doc.
Add the "arm,im-pd1-syscon" compatible which was not documented. Add
"ranges", "#address-cells", and "#size-cells properties which were
missing.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

'arm,realview-pb1176-syscon' is not one of ['arm,realview-eb11mp-revb-syscon', 'arm,realview-eb11mp-revc-syscon']
'arm,realview-eb-syscon' was expected
from schema $id: http://devicetree.org/schemas/mfd/arm,dev-platforms-syscon.yaml#
doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]
The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.
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 after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Thanks for cleaning this up. My excuse is that it happened in the
early days of schemas.
