Subject: [PATCH] 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.

The fix is similar to a708fb7b1f8dcc7a8ed949839958cd5d812dd939 but given
all the required logic already exists in mlx4_qsfp_eeprom_params_set()
only s/_LEN/MAX_LEN/ is needed.
