Subject: [PATCH v3 net-next 01/10] net: dsa: sja1105: enable the TTEthernet engine on SJA1110

From: Vladimir Oltean <vladimir.oltean@....com>

As opposed to SJA1105 where there are parts with TTEthernet and parts
without, in SJA1110 all parts support it, but it must be enabled in the
static config. So enable it unconditionally. We use it for the tc-taprio
and tc-gate offload.
