net/ice/base: support class 5+ modules

Currently QSFP/SFP modules up to power class 4 are supported.
100G modules require higher power in many cases.
Also, low power mode requires support of power classes 7 and even 8.

This change extends "Get Link Status" AQ command (0x0607) to
support class 5+ modules.

The patch also add couple other missing bits for link status.
