The C7xv-dsp on AM62A have 32KB L1 I-cache and a 64KB L1 D-cache. It
does not have an addressable l1dram . So, remove this optional sram
property from the bindings to fix device tree build warnings.

Also set the 'memory-regions' property as optional. This is because
the remote processors can function without carveout regions.

Changes since v1:
 - Corrected dsp node binding doc file to fix yamllint warnings for am62a.

That seems like an unrelated change that deserves its own commit..

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:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230810005850.21998-2-hnagalla@ti.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.
