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

+Changes only the required register bit in in PBI commands.

+Provides reference code which might needs some

+example:
+By default PBI_SRC=14 (which is for IFC-NAND/NOR) in rcw.cfg file
+which needs to be changed for SPI and SD.
+
+For SD-boot
+==============
+1. Set RCW[192:195], PBI_SRC bits as 6 in RCW file (t1040d4_rcw.cfg type files)
+
+example:
+ RCW file: board/freescale/t104xrdb/t1040d4_rcw.cfg

+
+2. SD does not support flush so remove flush from pbl, make changes in
