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

[Andy Fleming]

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",
