Subject: [PATCH v2] dt-bindings: firmware: brcm,kona-smc: convert to YAML

Convert Broadcom Kona family Secure Monitor bounce buffer bindings
to DT schema.

Changes during conversion:
- move from misc to firmware subdirectory
- add used, but previously undocumented SoC-specific compatibles
- drop deprecated compatibles (they've been deprecated for ~10 years)

Changes in V2:
- move to firmware subdirectory (Krzysztof)
- drop deprecated compatibles (Krzysztof)
- adjusted commit message to reflect the above changes

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.

You do not need oneOf.
