meta-facebook: minerva: Add blacklist config in entity-manager

Due to the CPLD on the fan board change to the XO5 starting from the DVT stage, we changed the update mechanism on it and we found that it caused the i2c bus to hang by FRUDevice initial process. So we add the i2c address of the CPLD update in the blacklist configuration to avoid this problem.
