Add devicetree bindings support for SM8450 SoC. Only the clocks are
different on this platform, rest is same as SDX55.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

doc reference errors (make refcheckdocs):

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

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.

You need to test the bindings with `make dt_binding_check`. This
requires an enum instead of two consts.


Best regards,
Krzysztof

Sorry! Usually I do but somehow missed on this series.
