- Updated RTL paths in various files to remove the 'ribp' prefix, reflecting the new directory structure. - Modified test descriptions to remove version indicators (e.g., V2, V3) for clarity and consistency. - Adjusted file references in scripts and tests to align with the new peripheral and multimedia directory structure. - Added a new test to ensure repository layout invariants, confirming the absence of deprecated paths.
