x86: base-files add support for Sophos 210r3 and 230r2

This fixes a previous commit for Sophos XG 210r3 which was missing
board_name mapping and adds support for the SG related version and the
XG/SG 230r2 which is the same hardware with a faster processor.

Sophos board_name mapping was modified to support all Sophos
SG/XG devices.

Sophos SG/XG 210r3 and SG/XG 230r2 are 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. The 210r3
and 230r2 only differ in the processor used.  This board update maps
eth1 (marked as WAN) as wan and eth0 and eth2-5 as lan.  Leaving the
two SFP ports unmapped.
