net/mlx4: Add support for EEPROM high pages query for QSFP/QSFP+/QSFP28 



Enable reading additional EEPROM information from high pages such as
thresholds and alarms on QSFP/QSFP+/QSFP28 modules.

"This is similar to commit a708fb7b ("net/mlx5e: ethtool, Add
support for EEPROM high pages query") but given all the required logic
already exists in mlx4_qsfp_eeprom_params_set() only s/_LEN/MAX_LEN/ is
needed.
