Given compatibility issues with external PNVM data that doesn't match the firmware it was designed with/for, future firmware releases will include the PNVM data in the firmware files directly, avoiding those mismatch issues. Make the driver load and use that embedded PNVM data in preference of external files, falling back to the external file if it isn't present.
