Subject: [PATCH] mpc83xx: mpc8360 rev.2.1 erratum 2: replace rgmii-id with
rgmii-rxid
u-boot itself uses GMII mode on the 8360. Fix up UCC phy-connection-type
properties in the device tree so the PHY gets configured for internal delay on
RX only by the OS, as prescribed by mpc8360 rev. 2.1 pb mds erratum #2.
