net: hns3: Add support for some CMIS transceiver modules 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8MV8N


CVE: NA

----------------------------------------------------------------------

Add two more SFF-8024 Identifier Values that according to the standard
support the Common Management Interface Specification (CMIS) memory map
so the hns3 driver will be able to dump, parse and print their EEPROM
contents.This two SFF-8024 Identifier Values are SFF8024_ID_QSFP_DD (0x18)
and SFF8024_ID_QSFP_PLUS_CMIS (0x1E).
