Subject: [net 6/7] i40e: Set PHY Access flag on X722

From: Adam Ludkiewicz <adam.ludkiewicz@...el.com>

The X722 FW API version 1.9 adds support for accessing PHY
registers with Admin Queue Command. This enables reading
EEPROM data from (Q)SFP+ transceivers, what was previously
possible only on X710 devices.
