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.

+ i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id", "sgmii",
+ "tbi", or "rtbi". This property is only really needed if the connection
