CMIS 4.0 document describes a universal EEPROM memory layout, which is
used for some modules such as DSFP, OSFP and QSFP-DD modules. In order
to distinguish them in userspace from existing standards, add
corresponding values.

CMIS 4.0 EERPOM memory includes mandatory and optional pages, the max
read length 768B includes passive and active cables mandatory pages.
