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. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
