Priyanka Jain 4b6067ae9d powerpc/T104xD4RDB: Add T104xD4RDB boards support
T1040D4RDB is a Freescale reference board that hosts the T1040 SoC.
    T1040D4RDB is re-designed T1040RDB board with following changes :
    - Support of DDR4 memory
    - Support of 0x66 serdes protocol which can support following interfaces
        - 2 RGMII's on DTSEC4, DTSEC5
        - 1 SGMII on DTSEC3
    - Support of QE-TDM

    Similarily T1042D4RDB is a Freescale reference board that hosts the T1040
    SoC. T1042D4RDB is re-designed T1042RDB board with following changes :
    - Support of DDR4 memory
    - Support for 0x86 serdes protocol which can support following interfaces
        - 2 RGMII's on DTSEC4, DTSEC5
        - 3 SGMII on DTSEC1, DTSEC2 & DTSEC3
    - Support of DIU
