x86: add board mapping for Sophos XG 210r3
Sophos XG 210r3 is a rackmounted x86 based firewall with 6 RJ-45 gigabit
ethernet ports (eth0-5) and 2 SFP gigabit ethernet ports (eth6, eth7)
all running Intel NICs supported by igb driver. This board update maps
eth0 (left most RJ-45 port) as wan and eth1-7 as lan.
