Subject: [PATCH 2/4] gianfar: Add phy-connection-type to gianfar nodes

The TSEC/eTSEC automatically detect their PHY interface type, unless
the type is RGMII-ID (RGMII with internal delay).  In that situation,
it just detects RGMII.  In order to fix this, we need to pass in rgmii-id
if that is the connection type.
