powerpc/t104xrdb: Add basic ethernet support
This covers only non-L2 switch ethernet interfaces i.e.
RGMII and SGMII interface for both T1040RDB and T1042RDB_PI
T1040RDB is configured as serdes protocol 0x66 which can
support following interfaces
2 RGMIIS on DTSEC4, DTSEC5
1 SGMII on DTSEC3
T1042RDB_PI is configured as serdes protocol 0x06 which can
support following interfaces
2 RGMIIS on DTSEC4, DTSEC5
