dt-bindings: arm-smmu: Add Tegra186 compatible string

The ARM SMMU instantiations found on Tegra186 and later need inter-
operation with the memory controller in order to correctly program
stream ID overrides.

Furthermore, on Tegra194 multiple instances of the SMMU can gang up
to achieve higher throughput. In order to do this, they have to be
programmed identically so that the memory controller can interleave
memory accesses between them.

Add the Tegra186 compatible string to make sure the interoperation
with the memory controller can be enabled on that SoC generation.

dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU

Every Qcom Adreno GPU has an embedded SMMU for its own use. These
devices depend on unique features such as split pagetables,
different stall/halt requirements and other settings. Identify them
with a compatible string so that they can be identified in the
arm-smmu implementation specific code.

Add specific compatible string for Marvell usage due to errata of

AP806 SoC uses the generic ARM-MMU500, and there's no specific
implementation of Marvell, this compatible is used for errata only.

The Arm SMMUv1 DT binding only allows combining arm,mmu-401 with

Allow this combination as well to let the Arm Juno board pass the test.

dt-bindings: Remove cases of 'allOf' containing a '$ref'

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

Convert the Arm SMMU binding to DT schema.

The existing binding doc doesn't cover the number of variations of
compatible properties found in .dts files. "qcom,msm8998-smmu-v2" was
also missing, so add it.

SoCFPGA Stratix10 has a single clock defined which doesn't match the
binding. This issue remains.
