Add compatible representing spi support on SA8255p.

Clocks and interconnects are being configured in firmware VM
on SA8255p platform, therefore making them optional.

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

yamllint warnings/errors:
./Documentation/devicetree/bindings/spi/qcom,spi-geni-qcom.yaml:90:11: [error] string value is redundantly quoted with any quotes (quoted-strings)

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240828203721.2751904-19-quic_nkela@quicinc.com

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.

Drop maxItems as 2 is already the max (with my change below).

Add blank line here.

No, keep all properties defined at the top-level and then add 
constraints in if/then schemas.

Do you see an example of this anywhere else? No. You need:

minItems: 1
maxItems: 2
