Subject: [PATCH v2 net-next] dsa:mv88e6xxx: allow address 0x1 in smi_init

From: Volodymyr Bendiuga <volodymyr.bendiuga@...termo.se>

Some devices, such as the mv88e6097 do have ADDR[0] external and so it
is possible to configure the device to use SMI address 0x1. Remove the
restriction, as there are boards using this address.
