Subject: [RFC PATCH net-next v2 6/9] net: sfp: Add more extended compliance codes

SFF-8024 is used to define various constants re-used in several SFF
SFP-related specifications.

Add SFF-8024 extended compliance code definitions for CMIS compliant
modules and use them in the next patch to determine the firmware flashing
work.
