Why I did it

Generating configuration using minigraph, when PFC WD is enabled, on system with more than 448 ports,
will lead to validation Error message since the allowed range for PFC WD POLL_INTERVAL (100..3000) will be violated.

This will happen if "enable_pfcwd_on_start" is set to "y". This configuation is taken from ini_config.json.

This PR set this flag to "disable" for SN5640 system in which PFC WD is not relevant for it as it doesn't work with lossless mode.
