    powerpc/83xx: add NAND support for the MPC8360E-RDK boards
    
    The StMicro NAND chip (512Mbit, 64MB) is connected to the local bus,
    the first local bus' user-programmable machine is configured by the
    firmware to work with NAND chips.
    
    QE GPIO pin is used to poll the NAND's Ready-Not-Busy signal.
