mpc83xx: mpc8360 rev.2.1 erratum 2: replace rgmii-id with rgmii-rxid

Browse Source 
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.
