board: ti: Clean up formatting in rm-cfg.yaml

Move to using the latest generated RM YAML configuration files generated
by the K3 Resource Partitioning Tool which updates them to have standard
formatting with respect to indentation.

These files were generated from the untagged commit 41718bd5f915 ("docs: Update
docs and move them to docs folder") of the K3 Resource Partitioning tool. This
tool is packaged as a part of the public SDK and is not otherwise
publicly available.
